mance when using the “COOR” and
“CRAB” modes.
If the axles become unsynchronized,
straighten the rear wheels first, then switch
the selector lever to the “2W” position and
straighten the front wheels. The driver may
then switch to “COOR” and “CRAB” and the
axles will again be synchronized.
2.7 TRANSMISSION OPERATION
If the oil temperature gauge, which is the
converter oil out temperature, rises
above 250° or the warning light comes
on, stop the vehicle immediately. Shift to
neutral and run the engine at 1000-1200
RPM. The temperature should drop rap-
idly to the engine water temperature. If
the temperature does not drop, trouble is
indicated. The trouble should be deter-
mined before the vehicle is operated
again.
Overheating generally occurs
due to working in too high of a gear ratio.
Shifting to a lower gear will help elimi-
nate overheating.
Do not shut off engine when unit is over-
heating.
2.8 SHUTTING DOWN THE TRACTOR
Bring tractor to a safe and complete stop
and set parking brake.
Place gear shift lever in neutral (N).
Turn off all lights.
Turn off ignition switch.
Always set the parking brake when parking
NOTE: The tractor. The automatic trans-
mission does not have an internal parking
lock.
2.9 EMERGENCY STOPPING
If the brakes fail, follow this procedure:
Downshift to next lower gear, unless al-
ready in “F1" or ”R1".
Use parking brake to stop tractor by pull-
ing on parking brake lever or pulling out
on the air parking brake button. When
towing a trailer with brakes, pull out on
the trailer air parking brake button to ap-
ply the parking brake.
2.10 TOWING THE TRACTOR
The tow tractor can be towed for 1 mile
maximum at no more than 3 MPH.
Towing longer will result in transmission
damage.
If the vehicle is to be towed, it will be nec-
essary to run the engine at idle speed to
lubricate the clutches.
If further towing is required, disconnect
the drivelines from the front and rear of
the transmission will be damaged.
Because of the design of the hydraulic
system, the engine cannot be started by
pushing or towing.
IMPORTANT! Failure to follow these in-
structions will void the warranty.
