1.2 Principles of sharpening

The reel type lawn mower cuts grass using theprinciplesofshears. It isnecessary, therefore, tohavetwosharpcuttingedgesmakingcloseenoughcontacttocutthegrasscleanly.Thisistheleastharmfulmethodofmowinggrass,becauseeachbladeofgrassissupportedbythebedknifewhilethereelbladeshears itoff. Thiseliminatesbleedingandbrowntopswhichoccurwhenthegrassiswhippedoffwithrotarytypemowers.

On a five bladed reel mower, the bed knife does five timestheworkofanyonereelbladeasallthereelbladesmust shear against it. The bed knife, therefore, is themaster cutting element and although made of heavierandhardersteels,it isimpossibletoproperlysharpenamowerwithdull reelbladeswithoutsharpening thebedknifetoo.

2.0 Locating the grinder

Determinewhereonaconcreteslabthegrinderwillbelocated.Thereelmountsontop.Theoperatorloadsandworksfromthefront. The grinder footprint is approximately 40” x 60” and we recommend about 6’ x 8’ of floor space with about 18” behind for walk behindmowers.

The Peerless requires standard 110volt,60Hz,singlephaseservice. Foreignversions with 200 volt, 50/60 Hz, singlephaseareavailable.Thegrindercomeswithan8footgroundedcordfor110voltservice.Thegrinderalsorequiresabout70psicleancompressedair.

2.1 Unpacking the grinder

While unpacking, examine carefully for anyshippingdamage.Anydamageshouldbereportedimmediatelytothecarrier.

By now you have removed the plasticwrap from the main crate. After removingthe box of accessories and any other optionalequipment,unboltthegrinderfromthe pallet and place it in the location youhaveselected.

2.2 Leveling the Base

Mount the levelingpadsprovided in tothefourcornersofthegrinder.

With the grinder in its final location, use a good quality carpenters level toadjust the levelingpadsuntilgrinder islevel.

2.4 Connecting the service

Make sure that all of the switches areturnedoff.

Connect the air supply to the filter regulatorandsetthepressuregaugeto50psi.

Plug the electrical cord into a 110 voltoutlet.

3. Preparing to Grind

3.0 Preparing the reel mower for grinding

Clean all dirt, grass, rust, grease, andoil from the mower assembly, especiallywhere it accumulates behind the lip of thebedknife.

Inspect for a wavy appearance orconditionalongthetopfaceofthebedknife.This would indicate that the bed knife hasbeen adjusted to the reel with excessive pressure. This could causewornor loosereelbearings.

1�

Checkthatthefrontspacerbarandthatthe bed knife is not loose. If the frame isloose,itisprobablyoutofalignment.Checkthe mower manufacturer’s manual to reset alignment.

Check the reel for free rotation andexamine the reel blades for bad nicks that mightindicateatwistorsprungspider.

Check to see that reel blades aresecurelyfastenedtothespidersandthatthespidersaresecureonthereelshaft.Repairasnecessary.

Check for axial and radial play in the reel bearings. Adjust or replace the bearingsin accordance with the manufacturer’s manual.

3.1 Mounting the reel mower for grinding

Placethereelmoweronthereelsupportrails.

Position the reel front tobackuntil thecenterofthereelshaftisabovethecenterofthegrindingwheelshaft.

Ifyouaregrindingwiththebedknifeinplace, locate the reel so that the grindingwheel will only grind the reel blades andclears the bed knife, front roller, and anyother part of the reel. If you are going torelief grind, you will need to leave enoughclearance between the reel blade and thebedknifeforthereliefgrindingmechanism.

3.2 Pi tape basics

Thepitapemeasuresthediameterofareelbywrappingaroundthecircumference.It is calibrated so that each inch is 3.142inches long or pi (π) inches long. This will automaticallyconvertthecircumferenceintoadiameter.

The pi tape also has a vernier, whichmakesitcapableofmeasuringthediameterofthereelto.001inches.

Makesure that thepi tape is tightandstraight.

18

Locate the zero (0) on the right sideor vernier side of the pi tape. Read themeasurement just above the zero. Eachlarge numbered line is 1 inch. Each smallnumbered line is .1 inchesandeachsmallline without numbers is .025 inches. Theillustrationattheleftwouldthenbe4.275.
