Neutral Adjustment
1.Be sure the dump valve levers are in the run position and the steering control levers are in the neutral lock position.
2.With an operator in the seat, start the engine and disengage the parking brake.
3.Run the engine at full operating speed and check if the machine creeps forward or backwards.
4.Adjust the RH wheel by loosening the jam nuts on the steering control rod and turning the rod until the drive wheel turns in the forward direction. Turn the rod back until the drive wheel stops moving. Turn the rod an additional 1/2 turn. See Figure

5.Tighten the jam nuts and repeat for the LH wheel. See Figure
6.Actuate the steering control levers forward and reverse several times and return them to the neutral position.

8.Check that the steering control levers hit the stop before the pumps reach full stroke. Adjust as needed.
Tracking Adjustment
Caution
Stop the engine and remove the key from the ignition before making any adjustments. Wait for all moving parts to come to a complete stop before beginning work.
Caution
The engine and drive unit can get hot during operation causing burn injuries. Allow engine and drive components to cool before making any adjustments.
- NOTE -
Before proceeding with this adjustment, be sure that the caster wheels turn plus pivot freely and that the tire pressure in the drive wheels is correct. If the tire pressure is not correct, the machine will pull to the side with the lower pressure.
1.If at full speed the mower pulls right, it is an indication that the left wheel is turning faster than the right wheel. To adjust this condition, proceed as follows:
A. Stop the machine and place the steering control levers in the neutral position. Loosen the lock nuts securing the ball joints at each end of the LH steering control rod. Rotate the control rod to lengthen the rod and tighten the lock nuts. This will cause the control rod to stroke the LH pump less, slowing down the LH wheel. See Figure
- NOTE -
If after making the adjustment as outlined in step 1A, the machine creeps forward or backward, perform the neutral adjustment. See Neutral Adjustment on page 23.
2.If at full speed the mower pulls left, it is an indication that the right wheel is turning faster than the left wheel. To adjust this condition, proceed as follows:
