▲ Never work under the machine or attachment unless itis safely supported with stands, blocks or a hoist.

▲ Do not touch hot parts of machine.▲ Never direct discharge of material from mower deck

towards bystanders. Do not operate the mowerwithout either the discharge chute or the entire grasscollection system in place.

▲ Always disengage the blades and wait for them to stopbefore crossing gravel drives, walks or roads.

▲ Always keep clear of the mower blades andattachments during their operation.

▲ Turn off blades when not mowing.▲ Slow down before turning.▲ Stop the engine before removing the grass catcher or

unclogging the discharge chute. Never clear thedischarge chute with the engine running. Turn off theengine and be sure the blades have stopped beforecleaning. Use a stick to clear a plugged discharge area.Never use your hand!

▲ Do not operate the machine while under the influenceof alcohol or drugs.

▲ Exercise caution when loading or unloading themachine onto a trailer or truck.

▲ Always wear safety goggles or safety glasses with sideshields when operating the mower.

▲ Data indicates that operators, age 60 years and above,are involved in a large percentage of riding mower-related injuries. These operators should evaluate theirability to operate the mower safely enough to protectthemselves and others from serious injury.

▲ Always disengage the blades and wait for them to stopbefore crossing gravel drives, walks or roads.

▲ Always keep clear of the mower blades andattachments during their operation.

▲ Never make sudden starts, stops, turns, or reversedirection, especially when maneuvering on slopes.The steering is designed for sensitive response. Rapidmovement of the steering lever in either directioncould result in a reaction of the tractor that can causeserious injury.

▲ If any attachment or additional weight is mounted onthe rear of the unit, any rapid movement of the controllevers in either direction could result in a reaction ofthe tractor that can cause serious injury.

▲ Use extreme caution when operating on slopes.• Be extremely careful changing directions on a slope.

Slow down.• Do not operate where the machine could slip or tip.

▲ Do not remove or modify the stabilizer wheels.▲ Remove obstacles such as rocks, tree limbs, etc.▲ Keep all movement on slopes slow and gradual. Do

not make sudden changes in speed or direction.▲ Avoid starting and stopping on a slope. If tires lose

traction, disengage the blades and proceed slowlystraight down the slope.

▲ Do not turn on slopes unless necessary, and then, turnslowly and gradually downhill, if possible.

▲ Do not mow near drop-offs, ditches, or embankments.The machine could suddenly turn over if a wheel goesover the edge of a cliff or ditch, or if an edge caves in.

▲ Do not mow on wet grass. Reduced traction couldcause sliding.

▲ Do not try to stabilize the machine by putting your footon the ground.

▲ Watch for holes, ruts or bumps. Uneven terrain couldoverturn the machine. Tall grass can hide obstacles.

▲ Keep children out of the mowing area and under thewatchful care of another responsible adult.

351254_07062-2

351254_0706 2-3

attachment bolts. Keep equipment in good condition.▲ Never tamper with safety devices. Check their proper

operation regularly.▲ Grass collection system components are subject to

wear, damage and deterioration, which could exposemoving parts or allow objects to be thrown.Frequently check components and replace withmanufacturer’s recommended parts, when necessary.

▲ Mower blades are sharp and can cut. Wrap theblade(s) or wear gloves and use extra caution whenservicing them.

▲ Use only genuine Hustler replacement parts to ensurethat original standards are maintained

▲ Do not remove or modify the stabilizer wheels.▲ The Hustler mower is capable of operating

horizontally (traverse) on moderately steep slopes.When operating on slopes up to 15 degrees, be awareof any conditions that may cause the tractor drive tiresto lose traction resulting in a possible loss of control ofthe machine. An operator should not operate on aslope until he is thoroughly familiar with theequipment.Do not operate the machine on slopes greater than15 degrees.

It is strongly recommended that the operator drivethe machine off of the slope, using extreme caution, ifany sign of loss of traction is detected. Wait until thecondition that caused the problem is resolved beforeattempting to operate on the slope again.

Terrain conditions can affect traction resulting inpossible loss of control of the machine. Some of theconditions to be aware of are:

1. Wet terrain2. Depressions in the ground; i.e. holes, ruts,

washouts3. Mounds of dirt4. Soil type; i.e. sand, loose dirt, gravel, clay5. Grass type, density, and height6. Extremely dry conditions of grass7. Tire pressure

The attachments mounted to the tractor will alsoaffect the way it handles on a slope. Be aware thateach attachment’s characteristics vary.

Another consideration to safe mowing on slopes isto be aware of what is located at the bottom of theslope. Extreme caution should be used when there is ahazard located at the bottom of the slope. Someexamples are:

1. Water; i.e. lake, river2. Cliffs, retaining walls3. Roads, highways4. Buildings5. Rocks

These are just a few examples of situations whencaution must be used when operating on a slope.There are many other possibilities too numerous tomention. Just remember to always exercise extremecaution when operating on any slope.

▲▲ Clean flammable material from machine. Preventfires by keeping engine compartment, battery,hydraulic lines, fuel line, fuel tank and operator’sstation clean of accumulated trash, grass clippings,and other debris. Always clean up spilled fuel andoil.

▲▲ Specific safety warning decals are located on theequipment near the immediate areas of potentialhazards. These decals should not be removed orobliterated. Replace them if they become non-readable.

351254_07062-4

Do not smoke while refueling.Do not fill tank with engine running,or while the engine is hot.Allow engine to cool before storingmachine inside a building.Store away from open flame or sparkif there is fuel in tank.Clean up any gasoline spills.Do not refuel while in enclosed traileror other enclosed areas

Avoid skin contact with battery acid.Always wear eye protection whenchecking the battery, acid can causeserious injury to skin and eyes. Ifcontact occurs, flush area with cleanwater and call physician immediately.Acid will also damage clothing.Do not allow open flame near thebattery when charging.Hydrogen gas forms inside thebattery. This gas is both toxic andflammable and may cause anexplosion if exposed to f lame.Always remove the negative groundfirst and replace it last.Do not overfill battery.Electrolyte may overflow anddamage paint, wiring or structure.When cleaning the battery, use soapand water. Be careful not to getsoap and water into the battery. Usesoda mixed in water to cleancorrosion off the terminals.

Hydraulic f luid escaping underpressure can penetrate skin.Hydraulic f luid may also causeinfection in a minor cut or opening inthe skin; if exposed to hydraulic fluid,see a doctor at once.Before applying pressure to hydraulicsystem, make sure all connectionsare tight and all hoses and lines arein good condition.Relieve all pressure in the systembefore disconnecting or working onhydraulic lines.To find a leak under pressure, use apiece of cardboard or wood – neveruse your hands.To relieve all pressure in system,turn engine off and lower attachment.

Read Owner’s Manual and QuickReference Decal before attempting to

operate this machine.

The following illustrations show the various safety decals that are located on the machine. A brief explanation is shown tohelp the operator understand the meanings of these decals.

Do not remove or modify stabilizerwheels or injury can result.Never stop suddenly while backingdown slopes. This action may resultin a reaction of the tractor that cancause serious physical injury.

Never operate the mower deck withside deflector removed or in raisedposition, except when the grasscatcher attachment is being used.

Hot surface!

Keep shields or covers in placewhile machine is in operation.Keep hands away from rotatingpulleys and belts.

Whirling blades! Keep hands andfeet away.Beware of thrown objects.

Avoid crushingDo not jump if machine tipsUse seat beltSeat belt must be fastened whileoperating this machine. Failure touse seat belt will result in seriousinjury in the event of a roll over.

Use seat belt.

This structure’s protective capabilitymay be impaired by structuraldamage, overturn, or alteration.To minimize chance of injury ordeath from rollover; keep ROPS inthe raised and locked position anduse the seat belt. There is no roll over protection whenthe ROPS is in the lowered position.Lower the ROPS only whenabsolutely necessary. Drive slowlyand carefully. Raise the ROPS assoon as clearance permits. Readand follow sloper operationinstructions and warnings.Do no wear seat belt when the ROPSis in the lowered position.

1. The operator must be on the seat when testing the seatswitch.

2. Set both control levers in the park brake position.3. Start the engine and allow it to warm up to operating

temperature.4. With the deck clutch switch down and the control

levers in the park brake position, slowly raise off of theseat. The engine should continue to run.

5. With the deck clutch switch up and/or the controllevers in the neutral position, slowly raise off of theseat. The engine should stop.

6. If the engine fails to stop when the deck clutch switchis up or one or both of the control levers is up(out ofthe park brake position) and the operator is off the seat,check the function of the seat switch. If the seat switchis not operating properly (is not opening or closing)and if the cause can not be determined, replace the seatswitch.

If the problem can not be located, contact your HustlerDealer.

WARNING: The safety interlock system shouldalways function per steps 4 and 5. If it does notfunction properly, it should be correctedimmediately. Do not operate machine withoutproperly functioning seat safety switch.

Engine startingThe Hustler Super Z Diesel safety start interlock system

is also designed to protect the operator and others fromaccidental injury due to unintentional engine starting. Theengine starting motor will not engage until:

A. Control levers are in the park brake position.B. Deck clutch switch is in the down (OFF) position.

WARNING: The safety interlock system mustnot be disconnected or bypassed.

NOTE: The operator’s seat is equipped with a separatesafety switch. If for any reason the operator should becomeunseated when the brake switches are disengaged or thedeck clutch switch is engaged the engine will stop.

The following steps are the correct procedures forstarting the engine. If difficulty is encountered, contact theHustler Dealer in your area.

1. Before starting tractor each day, perform daily pre-operation checking.

2. Make sure the control levers are in the park brakeposition and deck clutch switch is disengaged.

3. Set throttle at approximately 1/2 open position.

4. Insert key in ignition switch and rotate it to the ONposition, then hold the pre-heat switch down to pre-heat the engine, hold this position for 6 seconds. Thisis necessary only when the temperature is below 50o F.This operation is not necessary when restarting a warmengine.Shown in the chart are the standard preheating timesfor various temperatures. This operation, however, isnot required when the engine is warmed up.Failure to follow these recommendations can leadto premature failure of the starter motor and thefuel shut-off solenoid.NOTICE: Ether, or other starting fluids, mustnever be used as a starting aid with this engine.Warranty will be denied when engine damageresults from such use.

5. Rotate ignition switch key full clockwise to engagestarting motor. Release key when engine starts.

IMPORTANT: The engine starter should not beoperated for periods longer than 30 seconds at a time. Aninterval of at least two minutes should be allowed betweensuch cranking periods to protect the starter from overheatingand burn-out.

6. Perform test to make sure safety start interlock systemis operating properly. Refer to Safety start interlocksystem section.

7. As soon as engine begins to run, check to make certainthe oil warning light is off. If not, stop engineimmediately and check for the cause.

8. Allow the engine to idle a few minutes beforeadvancing the throttle and/or engaging the deck clutch.

9. Before stopping the engine, place the control levers inthe park brake position, disengage the deck clutch, andthrottle back to low idle for a couple of minutes; thenrotate ignition key counter-clockwise to the OFFposition. Remove the key from switch before leavingthe tractor.

WARNING: Never leave the machineunattended with key in ignition switch.

Bypass valve

Moving tractor with stalled engineIf it becomes necessary to move the tractor when the

engine is inoperative, the hydraulic pumps are equipped withbypass valves. Before moving the unit, turn bypass valvescounter clockwise one-half to one revolution. The valvestems on each hydraulic pump are located on the top of thepump and are identified as a hex stud. Figure 3-8

Do not tow the machine. Move it by hand or use a winchto load on a trailer for transporting.

When transporting on another vehicle, the tractor shouldbe facing forward and it must be secured.

IMPORTANT: Always make certain the two bypassvalves are returned to their operating position before runningthe tractor following repairs.

ROPSThe two-post ROPS can be pivoted down so that the

machine can operate under low hanging tree limbs or otherobstructions. Do not wear the seat belt when the ROPS is inthe lowered position. Fig. 3-10

WARNING: To minimize chance of injury ordeath from rollover: keep ROPS in the raisedand locked position and use the seat belt.There is no roll over protection when theROPS is in the lowered position.Lower the ROPS only when absolutelynecessary. Drive slowly and carefully. Raisethe ROPS as soon as clearance permits. Readand follow slope operation instructions andwarnings.Do not wear seat belt when the ROPS is in thelowered position.

Driving the tractor

DANGER: Never make sudden starts, stops orreverse direction, especially when going up aslope because the mower may tip backwards.The steering is designed for sensitive response.Rapid movement of the control levers in eitherdirection could result in a reaction of the tractorthat can cause serious injury.

After starting engine, engage the control levers and steeras follows:

To go forward, push control levers forward an equaldistance (Fig. 3-9).

To go in reverse, pull control levers rearward an equaldistance (Fig. 3-9).

To turn left, move the right control lever farther forwardfrom neutral than the left control lever.(Fig. 3-9)

To turn right, move the left control lever farther forward

from neutral than the right control lever. (Fig. 3-9)To pivot turn, move one control lever forward and the

other control lever back of neutral. This will allow the drivewheels to counter-rotate. (Fig. 3-9)

To stop or decrease speed, move control levers toneutral. When going forward pull back gently on controllevers. When going in reverse push forward gently oncontrol levers.

DANGER: When moving in the rearwarddirection push forward gently on control leversand avoid sudden movement. Any suddenmovement could cause the front of the mower tocome off of the ground resulting in possible lossof control.

WARNING: Never stop suddenly while backingdown slopes. This action may result in a reactionof the tractor that can cause serious physicalinjury.

To increase speed, increase control lever’s distance fromneutral. The farther forward control levers are from neutral,the faster tractor will travel forward. The farther backcontrol levers are from neutral, the faster tractor will go inreverse.

Operating suggestions

DANGER: Prior to operating the tractor theoperator should be thoroughly familiar with theproper use and operation of the equipment,should read the manual completely andthoroughly, and should have attempted slowmoving maneuvers to become familiar with theoperation of the equipment before attemptingnormal speed operation. An inexperiencedoperator should not mow on slopes or on uneventerrain.

WARNING: If you lose steering control whileoperating the machine, place the steeringcontrol levers in the park brake positionimmediately. Inspect the machine and involveyour Hustler dealer to resolve the problembefore continuing to operate.

WARNING: The unit’s control levers are veryresponsive: Easy does it! For smooth operation,move lever slowly, avoid sudden movement.Skill and ease of operation come with practiceand experience.

WARNING: Children or bystanders may beinjured if they move or attempt to operate thetractor while it is unattended. Always disengagedeck clutch, place control levers in park brakeposition, stop tractor engine, and remove ignitionkey when leaving operator’s seat.

Inexperienced operators may have a tendency tooversteer and lose control. Slow-moving practicemaneuvers are recommended to become familiar with thesecharacteristics before attempting normal speed operation.

WARNING: Sharp depressions or raisedobstacles (such as gutters or curbs) should not bedirectly approached at high speed in an attemptto “jump” them as the operator could be thrownfrom the equipment. Approach at a slow speedand angle one drive wheel at the obstruction.Continue at an angle until the wheel clears andthen pivot the opposite wheel around.

When turning on soft wet turf, keep both wheels rollingeither forward or backward. Pivoting on one stopped wheelcan damage turf. This is especially important whenmowing.

Tractor performance is maximum when the throttle is setat full rpm. This gives maximum power to the drive wheelsand deck when needed. Use the control levers to controlground speed rather than engine rpm.

WARNING: Do not operate the equipmentwhile wearing sandals, tennis shoes, sneakers,shorts or any type of loose fitting clothing.Always wear long pants, safety glasses, hearingprotection and safety shoes when operating thismachine.

Keep blades sharp. Many professional mowingcompanies have additional sets of blades and change bladestwice a day: once in the morning and again at noon. Manyproblems with incorrect cutting patterns are due to dullblades or blades which have been sharpened incorrectly.Information on sharpening blades is listed in this manual’smaintenance section. In addition, most communities haveindividuals or companies which specialize in sharpeningmower blades. Blade sharpness should be checked daily.

Use high blade speed. Your Hustler Super Z Diesel isdesigned to operate at full throttle. The throttle settingdirectly controls blade speed. The highest blade speedgenerally gives best cut.

area. Select a mowing pattern that directs grass dischargetowards the outside, not towards center, of mowing area.Generally, this means using a pattern utilizing left turnsbecause side discharge (Fig. 3-11) is to right. In any case,avoid throwing grass discharge onto unmowed area becausegrass is then mowed “twice”. Mowing twice puts anunnecessary load on the unit and reduces mowing efficiency.

When mowing a lawn for the first time cut grassslightly longer than normal to avoid scalping uneven terrain.When possible, it is best to use the cutting height that wasused in the past. When cutting grass taller than six inches,you may want to mow the lawn twice to achieve a betterquality of cut.

During normal mowing cut only about 1/3 of the grassblade. Cutting more than that is not recommended unlessgrass is sparse or it is the end of the mowing season.

Alternate mowing direction to keep the grass growingstraight and better dispersion of the clippings.

Remember, grass grows at different rates at differenttime of the year. Mow more often in the early spring tomaintain the same cutting height. As the growth rate slowsin mid summer, mow less frequently. If you cannot mow ata regular interval, mow at a high cutting height; then mowagain two days later at a lower cutting height.

Raise the cutting height of the mower if the cuttingwidth of the mower is wider than the previous mower. Thisensures that uneven turf is not cut too short.

Raise the cutting height of the mower if the grass ifslightly taller than normal or if it contains a high degree ofmoisture. Then mow it again with the cutting height setlower.

If the machine’s forward motion must be stopped whilemowing, a clump of grass clippings may drop onto yourlawn. To avoid this, move onto a previously cut area withthe blades engaged.

WARNING: Never direct discharge of materialfrom mower deck towards bystanders.

WARNING: Never operate the mower deckwith discharge chute removed or in raisedposition.

WARNING: Always check area to be mown forrocks and other debris before mowing.

Mower deck operation

DANGER: Never attempt to make anyadjustments to the mower deck while the engineis running or with the deck drive clutch engaged.Mower blades cannot be seen and are locatedvery close to deck housing. Fingers and toes canbe cut off instantly.

With the engine running, engage the deck clutch switch(Fig. 3-2) and advance engine throttle to full rpm.

NOTE: Engaging the deck clutch at high engine rpm orwhen under heavy load (in tall grass for example) can causebelts and/or electric clutch to slip, resulting in prematurewear or possible damage.

REFERENCES:a — Refer to Engine Owner’s Manual

NOTE: After completing maintenance cycle (500hours), repeat cycle.

IntroductionWARNING: Unless specifically required, DONOT have engine running when servicing ormaking adjustments to tractor. Place controllevers in the park brake position, disengage deckclutch, and remove ignition switch key. Repairsor maintenance requiring engine power should beperformed by trained personnel only. To preventcarbon monoxide poisoning, be sure properventilation is available when engine must beoperated in an enclosed area. Read and observesafety warnings in front of manual.

DANGER: Before working on or under thedeck, make certain engine cannot be accidentallystarted. Shut engine off and remove ignition

switch key for maximum safety. Repairs ormaintenance requiring engine power should beperformed by trained personnel only.

DANGER: Exercise caution when workingunder the deck as the mower blades areextremely sharp. Wearing gloves is advisablewhen working around or with the blades.

WARNING: Except when changing or checkingbelt, always keep belt covers on mower forsafety as well as cleanliness.

Regular maintenance is the best prevention for costlydowntime or expensive, premature repair. The followingpages contain suggested maintenance information andschedules which the operator should follow on a routinebasis.

Remain alert for unusual noises, they could be signalinga problem. Visually inspect the machine for any abnormalwear or damage. A good time to detect potential problemsis while performing scheduled maintenance service.Correcting the problem as quickly as possible is the bestinsurance.

WARNING: Keep your machine clean andremove any deposits of trash and clippings,which can cause engine fires and hydraulicoverheating as well as excessive belt wear.

Clear away heavy build-up of grease, oil and dirt,especially in the engine and hydraulic reservoir area; minutedust particle are abrasive to close-tolerance engine andhydraulic assemblies.

Daily inspect mower for grass clippings and wire andstring tangles. The underside of the mower deck will collecta build-up of grass clippings and dirt, especially when grassis wet or has high moisture content. This build-up willharden, restricting blade and air movement and willprobably show a poorer quality of cutting. Therefore itshould be removed routinely.

To do this it will be necessary to raise and block the deckin the full up position and scrape the build-up fromunderneath.

WARNING: When possible clean under mower,using a stick or similar instrument making surethat no part of the body, especially arms andhands are under mower.

Some repairs require the assistance of a trained servicemechanic and should not be attempted by unskilledpersonnel. Consult your Hustler service center whenassistance is needed.

Solid fill tires are not recommended for Hustler turfequipment. On any machine, with solid filled tires, thewarranty claim will be denied.

WARNING: Explosive separation of a tire andrim can cause serious injury or death.Do not attempt to mount a tire without the properequipment and experience to perform the task.Always maintain the correct tire pressure andnever over inflate.Never weld or heat a wheel and tire assembly asan explosion may occur. Welding can weaken ordeform a wheel.When inflating tires stand to one side and not infront of or over the tire assembly.Check tires for low pressure, blemishes, damagedrims or missing lug bolts and nuts.

Hour meterTo recognize when your machine needs servicing, check

the hour meter and the maintenance schedule. The hourmeter shows the number of hours the engine has run and themaintenance schedule lists the service intervals. Fig. 4-2

LubricationGrease the following areas per the Maintenance

Schedule. Use SAE multi-purpose grease.1. Front gauge wheel bearings 2. Four deck lift pivots, located to the side of the

operator’s footrest3. Deck idler4. Pump idler pivot5. Two deck pusher arm pivots6. Blade spindle assemblies The spindle assemblies

require lubrication annually. Each spindle shaft isequipped with a grease zerk located under the deck.Use no more than one or two ounces of SAE multi-purpose grease, (1 to 2 pumps on an average greasegun). Do not force lubricant in to grease zerks.Bearings are sealed and do not require muchlubricant.

Electrical systemThe electrical system is a 12 volt, negative ground.

Recommended battery size is a garden tractor BCI groupU1R with 225 or better cranking AMP rating. Twomaintenance-free batteries are recommended. Otherwise,follow battery manufacturer’s maintenance, safety, storingand charging specifications.

WARNING: Shorts caused by battery terminalsor metal tools touching metal tractor componentscan cause sparks. Sparks can cause a battery gasexplosion which will result in personal injury.Prevent the battery terminals from touching anymetal tractor parts when removing or installingthe battery.Do not allow metal tools to short between thebattery terminals and metal tractor parts.

WARNING: Incorrect battery cable routingcould cause damage to the tractor and batterycables. This can cause sparks which can cause abattery gas explosion which will result inpersonal injury.Always disconnect the negative (black) batterycable before disconnecting the positive (red)cable.

Common circuit failures are usually caused by shorting,corroded or dirty terminals; loose connections, defectivewire insulation or broken wires. Switches, solenoids andignition components may also fail, causing a shorted or opencircuit.

Before attempting any failure diagnosis of the electricalsystem, use a test light or voltmeter to check the batteryvoltage. If the battery voltage is satisfactory, check thecleanliness and tightness of the terminals and groundconnections. A general understanding of electrical servicingand use of basic test equipment is necessary fortroubleshooting and repair.

Major overhaul or repair of the starting motor oralternator should be performed by trained technicians only.

Access to engine and hydraulicpumps

The hydraulic pumps are accessed by lifting the seat

platform. The seat platform is hinged at the front. To raiseit, release seat latch and tilt seat platform up and forward.The seat platform catch (Fig. 4-4) will prevent the seat fromgoing all the way over. However, if more access is desiredunder the seat platform, the seat platform catch can be raisedallowing the seat to pivot more. Make certain to place thecontrol arms in the park brake position and pivot thearm rests upward before placing the seat platform in thefull forward position to prevent arm rest damage.

The engine can be accessed from the rear of the machinewithout removing the engine shroud. If additional access isrequired, remove the engine shroud.

WARNING: Always wear adequate eyeprotection when servicing the hydraulic systemand battery.

Hydraulic systemIMPORTANT: Never use hydraulic or automatic

transmission fluid in this system; use only motor oil asspecified. Remember, dirt is the primary enemy of anyhydraulic system.

WARNING: Hydraulic oil escaping underpressure can penetrate skin. Hydraulic oil maycause infection in a minor cut or opening in theskin. If exposed to hydraulic fluid, see a doctorat once.

Before applying pressure to hydraulic system,make sure all connections are tight and all hosesand lines are in good condition. To find a leakunder pressure, use a piece of cardboard or wood— never use your hands. Relieve all pressure inthe system before disconnecting or working onhydraulic lines. To relieve pressure, lower allattachments and shut off engine.

The 2.0 U.S. gallon (7.57 liter) hydraulic reservoir is partof the radiator housing. The fill neck is the left neck on thetop of the radiator housing. Fig. 4-5

Check oil level in hydraulic system after every 50 hoursof operation or weekly, whichever occurs first. Check moreoften if system appears to be leaking or otherwisemalfunctioning.

Fluid level should be 3” from the top of fill neck on unitsequipped with a vented reservoir cap. On units equippedwith a non-vented reservoir cap the fluid level should be 2”from the top of fill neck. Use only Mobil 1 15w-50synthetic oil.

Change hydraulic system filter element and reservoir oil(Fig. 4-6) after first 50 hours of tractor operation, then at 300hours and then every 500 hours or annually, whichevercomes first, thereafter. Use only Mobil 1 15w-50 syntheticoil. Do not use Lubrizol additive with Mobil 1 15w-50synthetic oil.

The system filter is located next to the left drive wheel on

the tractor frame. A standard oil filter wrench is used tochange filter, threads are right handed. Use a Hustlerapproved filter element only.

IMPORTANT: Prefill the filter element with clean oil,before installing, to prevent drawing air into the systempump.

NOTE: Install new hydraulic filter element immediatelyafter the removal of the old filter to minimize oil loss fromreservoir.

1. Fill the filter element with clean system oil. Smear alight coating of oil on upper surface of rubber seal.

2. Install the filter element on base. Tighten the oil filterby hand until the filter seal makes contact with thefilter head, then tighten an additional 3/4 - 1 turn withan oil filter wrench. — DO NOT OVERTIGHTEN.

3. Start tractor engine and let run at approximately 2/3throttle for a few minutes to work any trapped air outof the system before engaging the steering controllever.

4. Stop the engine and check the filter and connectionsfor leaks.

5. Check the hydraulic reservoir for specified oil level.Add clean oil as necessary.

Clean or replace hydraulic reservoir cap annually. Capmay be cleaned by dipping in or flushing with cleaningsolvent. Follow manufacturer’s instructions and warningsfor application of solvent type selected.

A hydraulic oil heat exchanger is installed on the Super ZDiesel. This heat exchanger is designed to keep hydraulicsystem oil temperature lower in hot operating conditions orheavy continuous operating conditions.

This hydraulic heat exchanger is part of the radiatorhousing. The air is drawn across the cooling fins by the leftelectric fan located to the rear of the radiator housing. Fig.4-6

NOTE: The electric fans will perform a test cycle wherethey will push the air and then will auto reverse and pull airbefore reversing and pushing the air.

The deck blades are powered by a hydraulic motor. Thismotor provides power to the deck spindle drive belt. Fig. 4-7

Fuel system

WARNING: Observe usual fuel handlingprecautions; do not smoke while refueling, do notfill tank with engine running or while engine ishot; allow engine to cool before storing machineinside a building, keep fuel away from openflame or spark and store machine away fromopen flame or spark if there is fuel in the tank.Read and observe safety precautions at front ofthis manual.

WARNING: Fuel System Under Pressure! Thefuel system operates under high pressure, and thefuel filter and fuel line used must be approvedsystem components only. Use of substitute partscan result in system failure, fuel leakage andpossible explosion.

The fuel tanks are located in the tractor’s fenders. (Fig.4-8) Total capacity for the fuel tanks is 18 U.S. gallon (68.1liter)

This engine requires number 2 diesel fuel only. The fuelfilter is located on the left, rear side of the engine. Changefilter after every 100 hours of operation or annually,whichever occurs first. Fig. 4-9

When replacing the fuel filter, check the fuel line hosesfor any cracks or leaks. Replace as needed.

Super Z Diesel tractors are equipped with a fuel shutoffvalve located to the right rear of the seat (Fig. 4-10). Rotatethe valve to the middle position (shown) to allow fuel toflow from the right fuel tank to the fuel pump. The rightposition prevents fuel flow to the fuel pump. The leftposition allows fuel to flow from the left fuel tank to the fuelpump. Close this valve to prevent fuel flow to the enginewhen servicing the fuel system or when transporting the uniton a trailer or truck.

Diesel engines are subject to air blockage whenever thefuel tank runs empty, the fuel filter has been removed, anyfuel lines have been disconnected or removed and replaced,or when the tractor has been stored for a period of time.Should such air blockage occur, it will be necessary to bleedthe system, removing any trapped air between the fuel tankand filter, then trapped air between the filter and injectorpump as follows:

1. Fill the tank with fresh fuel and make sure the shut-offvalve is open at tank.

2. Loosen the vent screw (Fig. 4-9) located on top of thefuel filter and leave it open until air bubbles are nolonger present, then close the vent screw.

3. Start the engine and run at low rpm for 15 to 30seconds to expel air from pump, then close the air ventscrew.

4. If engine fails to start, repeat steps 2, 3 and 4.

Air service indicatorThe Super Z Diesel has an air service indicator installed

in the air cleaner. Fig. 4-13 & 4-14Replace the element whenever the service indicator

reaches the change filter red line. Check the indicator dailyand replace element as needed or annually whichever occursfirst.

Reset the indicator by pushing in on the yellow buttonafter each element change. Fig. 4-14

A service indicator takes the guesswork out of air cleanerservicing and allows you to safely benefit from the filter’soptimum performance.

Safety filterThe Super Z Diesel is equipped with a safety filter. The

filter element slides over the safety filter. Use Hustler partnumber 785279 only when replacing the safety filter.

NOTE: The safety filter does not require servicing unlessit becomes contaminated with dirt or moisture.

Recommended service procedureMany engine failures can be attributed to improper air

cleaner servicing. Ingested dust and dirt will cause cylinder,piston and bearing damage in a few hours. “Dusted”engines will result from:

1. Overservicing the air filter element.2. Improper installation.3. Damaged filter, seals or canister.4. Incorrect air filter element size.5. Use of poorly designed aftermarket air filter elements.Air cleaner servicing is an inexpensive maintenance

check that can prevent costly non-warrantable prematureengine damage.Overservicing

Overservicing occurs when an air filter element isremoved for cleaning or replacement before it is necessary.Each time the filter is removed a small amount of dirt anddust could fall in the intake system. This accumulated dirtcan cause a dusted engine. It only takes a few grams ofingested dirt over the normal service life of an engine tocause a dusted engine.

Do not clean element, replace with a new element only.Cleaning used air filter elements, through improper cleaningprocedures, can get dust on the inside of the filter causingdirt ingestion and engine failure.

It is important to note that whenever an air filter elementis cleaned by any method, the person or companyperforming the cleaning assumes responsibility for theintegrity of the filter from then on. The Donaldsonwarranty for air filters expires upon cleaning orservicing in any manner because the condition of thefilter after servicing is completely out of their control.Therefore, on a dust ingested engine failure, there will beno warranty consideration if the air filter element hasbeen cleaned or serviced in any manner.

A partially dirty air filter element works better than anew element. Therefore, a dirty filter element is not bad forthe engine unless it is excessively restricting the air flow andengine performance is affected. The reason is simple. Themedia in the filter must be porous to allow air to passthrough it. When dirty air passes through the filter, the dirtplugs some of the holes in the media and actually acts aspart of the filter media. When the next round of dirt enters,the first dirt helps filter out even smaller particles makingthe filter more efficient at stopping dirt from entering theengine. This is referred to as barrier filtration.

Of course, at some point the filter media becomes tooclogged to allow air to pass.

The mowing conditions will determine the frequency ofair filter element changing. Improper installation of an air filter element

Dust must not leak past the seals on each end of the airfilter element. The filter must be aligned within the canisterand properly seated for an effective seal so that no dirt canenter the engine. Damaged filter, seals or canister

Never bang or bump the filter element against the tire orany solid object, as dust and dirt particles will be forcedthrough the media causing continual passing of dirt into theengine. Visually inspect the outside of the air cleaner

Cooling systemEngine cooling is accomplished with circulated water and

Ethylene Glycol mixture. The radiator is equipped with apressure cap and recovery tank. System capacity isapproximately 3.0 U.S. gallon (11.36 liter). A 50-50mixture is recommended for all season operation. Thismixture provides freeze protection to -32 degrees F (-35degrees C). Should temperatures fall below this level,additional Ethylene Glycol must be added to the mixture.

Visually inspect the system daily prior to operatingtractor. Check coolant level in the recovery tank located tothe front left of the radiator assembly (Fig. 4-15). When theengine is cold there should be 1” (2.54 CM) of coolant in therecovery tank. When adding coolant, pre-mix the solutionbefore adding it to the recovery tank. It is not necessary toremove radiator cap for adding small amounts of coolant tosystem.

DANGER: Never remove radiator cap whenengine is hot. Pressurized hot steam and watermay be released, causing serious burns orpossible blindness.

canister periodically for external damage and replace ifnecessary.Incorrect air cleaner element

Use only the correct Donaldson air filter element, Hustlerpart number 785261, which is designed to fit the canisterproperly.

Hustler air filter elements have the correct mediacomposition, filter area, micron size and dimensions.Always use genuine Hustler filters. Many aftermarketfilters have been found to be incompatible with Hustler’scanisters and engines.

The air filter must remain intact to block passage of dirtand foreign particles from entering the engine. Beinginclined to disbelieve the need for more expensive air filterelements used on diesel engines may cause some individualsto opt for a less expensive part.

The filter element must be sufficient size andconstruction to withstand stresses, caused by rapid cyclingof the air volume demanded by the engine, without crackingor tearing under fatigue and pressure (especially dieselengines). Therefore, Hustler Turf Equipment and the enginemanufacturers have carefully selected a reliable filterdesigned to fit the needs of the engines. The filter specifiedis a Donaldson filter, Hustler part number 785261.

Owners should be reminded that failure to use originalequipment replacement parts is an “alteration” and will notbe considered for warranty in the event of engine damage.Recommended service procedure

1. Release clamps and remove element. Clean thecanister with a damp cloth.

2. Before installing a new element, inspect it by placing abright light inside and rotate the element slowly,looking for any holes or tears in the paper. Also checkgaskets for cuts or tears. Do not attempt to use adamaged element which will allow abrasive particlesto enter the engine.

3. Reinstall the dust cup. Make sure it seals all the wayaround the air cleaner body, then tighten the clamps.

4. Check all fittings and clamps periodically for tightnessand inspect hoses for holes or cracks.

5. Periodically check the intake hose for signs of ingesteddust. Locate and repair the source of ingested dirt.

The system should be drained, flushed and refilled withfresh solution after every 500 hours of operation.

If frequent refilling is necessary or if coolant appearsrusty, thoroughly check the system. Refer to the enginemanual for information on checking and cleaning system.

The air is pushed across the radiator cooling fins by theright electric fan located at the rear of the radiator housing.Keep the radiator and hydraulic heat exchanger area clean atall times and make sure trash is not allowed to accumulate,nor allow the fins and cores to become plugged.

NOTE: The electric fans will perform a test cycle wherethey will push the air and then will auto reverse and pull airbefore reversing and pushing the air.

Never force anything into the radiator fins which maybend or distort them. For cleaning, use compressed air only.

General engine maintenanceDetailed instructions and recommendations for break-in

and regular maintenance are specified in the EngineOwner’s manual. Please refer to this manual for engineservicing, lubricating oil levels with quality and viscosityrecommendations, bolt torques, etc. The engine warranty isbacked by the manufacturer. Special attention should bepaid to applicable data which will not be duplicated here.

IMPORTANT: Refer to the Caterpillar engine owner’smanual for specific cleaning instructions.

Belt replacementFigures 4-17, 4-18 and 4-19 show diagrams and

descriptions of the unit’s belt drive systems.Inspect these belts frequently for wear and serviceability.

Replace a belt that shows signs of severe cuts, tears,separation, weather checking and cracking, or burns causedby slipping. Slight raveling of belt covering does notindicate failure, trim ravelings with a sharp knife.

WARNING: If the pump belt fails, loss ofcontrol will occur especially when operating on aslope. If you lose steering control whileoperating the machine, place the steeringcontrol levers in the park brake positionimmediately. Inspect the machine and involveyour Hustler dealer to resolve the problembefore continuing to operate.

Inspect the belt pulley grooves and flanges for wear. Anew belt, or one in good condition, should never run againstthe bottom of the groove. Replace the pulley when this isthe case, otherwise belt will lose power and slip excessively.

Never pry a belt to get it on a pulley as this will cut ordamage the fibers of the belt covering.

Keep oil and grease away from belts, and never use beltdressings. Any of these will destroy the belt composition ina very short time.

Mower blade maintenanceCheck the mower blades daily, they are the key to power

efficiency and well groomed turf. Keep them sharp, a dullblade will tear rather than cut the grass, leaving a brownragged top on the grass within a few hours. A dull bladealso requires more power from the engine.

Replace any blade which is bent, cracked or broken.

WARNING: Never attempt to straighten a bentblade by heating, or weld a cracked or brokenblade as the blade may break and cause seriousinjury.

DANGER: Never work with blades whileengine is running or deck clutch is engaged.Always place deck clutch in the disengagedposition, place steering control levers in the park

brake position and turn engine off. Block upmower when you must work under it. Weargloves when handling blades. Always check forblade damage if mower strikes rocks, branchesor other foreign object during mowing!

Mower blade removalUse a 15/16" wrench to remove the 5/8" cap screw

holding the blade to the spindle shaft from underneath.Sharpen the blades on a grinder following pattern as

shown (Fig. 4-20). Touch-up sharpening can be done with afile.

Check the blades for balance following grinding. Acommercial balancing tool is available through mosthardware supply stores, or balancing can be done by placingthe blade on an inverted line punch or 1/2" bolt. Bladeshould not lean or tilt. Spin the blade slowly, blade shouldnot wobble. If blade is out of balance, true it up beforereinstalling.

Lay the blade on a flat surface and check for distortion(Fig. 4-21 and 4-22). Replace any distorted blade.

Do not re-use spindle bolts which have stripped, worn orundercut threads. Torque bolts on spindles to 118 foot-pounds (160.0 Nm) when reinstalling blades.

WARNING: When mounting blades, rotatethem after installation to ensure blade tips do nottouch each other or sides of the mower.

WARNING: Failure to correctly torque the boltmay result in the loss of the blade which cancause serious injury.

WARNING: Mower blades are sharp and cancut. Wrap the blade(s) or wear gloves and useextra caution when servicing them.

ADJUSTMENTS

IntroductionWARNING: Unless specifically required, DONOT have engine running when servicing ormaking adjustments to tractor. Place controllevers in the park brake position and removeignition switch key. Repairs or maintenancerequiring engine power should be performed bytrained personnel only. To prevent carbonmonoxide poisoning, be sure proper ventilationis available when engine must be operated in anenclosed area. Read and observe safety warningsin front of manual.

Your Super Z Diesel was adjusted before it left thefactory and was checked during predelivery setup.However, after start-up and break-in some adjustmentscould change.

Remain alert for unusual noises, they could be signalinga problem. Visually inspect the machine for any abnormalwear or damage. A good time to detect potential problemsis while performing scheduled maintenance service.Correcting the problem as quickly as possible is the bestinsurance.

WARNING: Keep your machine clean andremove heavy deposits of trash and clippings,they can cause engine fires and hydraulicoverheating as well as excessive belt wear.

Clear away heavy build-up of grease, oil and dirt,especially in the area of reservoir oil and engine combustionair; minute dust particle are abrasive to close-toleranceengine and hydraulic assemblies.

Some repairs require the assistance of a trained servicetechnicians and should not be attempted by unskilledpersonnel. Consult your Hustler service center whenassistance is needed.

Torque values

WARNING: Particular attention must be givento tightening the drive wheel lug nuts, wheelmotor nuts, and blade spindle bolts. Failure tocorrectly torque these items may result in theloss of a wheel or blade, which can cause seriousdamage or personal injury.

Torque values given below:Ft-lbs. Nm

Wheel (lug) nuts ................................65-75 ......88.14-101.7Wheel motor nut ...........................350-375 .....474.6-508.5Blade spindle bolt top ........................65-75 ......88.14-101.7Blade spindle bolt bottom ....................118 ................160.0
