The implement control levers for the D10R are not mechanically connected to the dozer andripper control valves. The blade control lever (1) and the ripper control lever (2) are inputdevices to an Electronic Control Module (ECM) located below the implement control levers.

Moving the blade control lever forward or rearward LOWERS or RAISES the blade. Movingthe lever left or right allows the blade to TILT LEFT or TILT RIGHT. The thumb lever (3)allows the operator to PITCH the blade forward or rearward.

The left button (4) on the blade control handle allows the operator to activate the AutomaticMode and the right button (5) cancels the Automatic Mode, so that the blade may be controlledmanually.

Located on the front of the blade control handle is a trigger switch (not visible). When thisswitch is engaged, the blade will PITCH FORWARD to dump the blade load. The trigger switchperforms the same function as the thumb lever when moved to the right.

Ripper RAISE and LOWER positions are controlled by the thumb switch (6) at the front of theripper control lever. The finger switch (7) allows the operator to control SHANK IN andSHANK OUT. Pushing the button (8) on the ripper control lever raises the ripper to maximumheight or moves the ripper tip to the full SHANK IN position.

Also located in this view are the throttle control switch (9) and the horn switch (10).

POWER TRAIN

Major changes to the D10R power train include a five-section pump and an updated Power TrainElectronic Control System.

The D10R is equipped with an Electronic Clutch Pressure Control (ECPC) transmission similarto the medium size track-type tractor transmissions. The ECPC transmission includes fiveproportional solenoid valves that are electronically modulated. Each solenoid valve directs oil toa single clutch in the transmission. In the current D10R, the transmission solenoids are ON/OFFsolenoid valves and modulation is done hydraulically.

The priority valve which is housed in the priority valve and lube management valve group iselectronically controlled by the Power Train ECM. The priority valve allowstransmission/torque converter charging section oil (A) to supplement transmission chargingsection oil (D) when the engine speed is below 1485 rpm, during a transmission shift, or whenthe power train oil is cold.

Shown is a sectional view of an ECPC transmission valve. The Power Train ECM controlstransmission shifting by modulating the current to the ECPC solenoid valves, which varies theoil pressure to the clutches.

Increasing the current forces the shaft to the right, which pushes the ball to the right and restrictsthe oil flow to drain. The reducing spool also moves to the right due to the pressure increase inthe chamber at the left of the orifice. This movement allows more oil to flow from the supplypassage, across the metering surfaces to the clutch. As the spool moves to the right, the ballreduces the rate of internal oil flow to drain.

IMPLEMENT HYDRAULIC SYSTEM

The D10R is equipped with an Electro-hydraulic Implement Control System similar to theD11R, which controls the hydraulic pilot valves for the blade and ripper.

The Implement ECM receives input signals from the blade control lever position sensors, rippercontrol lever position sensors, and various other sensors and switches. The ECM sendscorresponding output signals to energize the appropriate pilot solenoid valves on the electro-hydraulic manifold. The proportional solenoid valves control the amount of pilot oil thatis sent to the dozer or ripper control valves to shift the appropriate spools and direct main pumpoil to the head or rod end of the cylinders.

The ECM also sends corresponding output signals to energize the pitch and single tilt ON/OFFsolenoid valves on the dual tilt valve. The pitch and single tilt ON/OFF solenoid valves directoil to shift the dual tilt valve, which determines blade tilt and pitch angles.

The ECM controls the blade height, blade tilt, blade pitch, ripper height, and ripper shank in orout functions.

The implement system for the D10R is operated by pilot oil. The fan pump supplies pilot oil tothe electro-hydraulic pilot manifold, which includes an ON/OFF implement lockout solenoidvalve that allows oil flow to the proportional solenoid valves or blocks oil flow to the solenoidvalves. The accumulator provides pilot oil for lowering the blade with a dead engine.

The four proportional solenoid valves control the amount of pilot oil directed to the dozercontrol valve. This pilot oil is sent to the ends of the tilt or lift spool and control BLADE LIFT,BLADE LOWER and FLOAT, BLADE TILT LEFT, and BLADE TILT RIGHT.

If the tractor is equipped with a ripper, the pilot manifold is equipped with two additional bolt-onblocks. These blocks also contain four proportional solenoid valves that direct pilot oil to theripper control valve to select RIPPER RAISE, RIPPER LOWER, SHANK IN, and SHANKOUT. The ripper proportional solenoid valves control the amount of pilot oil directed to theripper control valve.

The electro-hydraulic pilot manifold also includes two pressure reducing valves and a shuttlevalve. One pressure reducing valve regulates the pilot supply oil pressure and the other pressurereducing valve regulates the resolved oil pressure from the logic valve. The shuttle valve directsthe highest oil pressure (pilot supply oil or resolved logic valve oil) to the proportional solenoidvalves.
