Control Linkage Adjustment
If any of the following conditions are noticed, the control
linkage must be adjusted.
l
Mower creeps when the direction control levers are
positioned in neutral with the neutral locks.
l
Mower creeps when the forward speed control levers are
in neutral.
l
Mower will not track straight when the forward speed
control levers are even.
Before beginning the adjustment procedure, check the tires
for correct inflation and even wear. Worn or incorrectly
inflated tires can cause tracking problems. Check the
hydrostatic oil level. Operate the mower to bring the
hydrostatic oil up to operating temperature
At times during this adjustment procedure, you must run the
engine. Be sure there is adequate ventilation.
Direction Control Linkage Adjustment
Perform this adjustment if the mower creeps when the
direction control levers are locked in neutral with the neutral
locks.
1. Raise and support the rear of the mower so that the rear
wheels are clear of the ground.
2. Lock the direction control levers in neutral with the neutral
locks.
3. Move the forward speed control levers full forward so that the
rollers do not contact the pump levers.
4. Adjust the direction control linkage on each side so that the
control arms on the side of each pump are vertical.
5. Hold an operator presence lever down on the hand grip for
the length of this procedure.
6. Start the engine and move the throttle lever to FAST.
7. Loosen the locknuts and adjust the direction control linkage
on each side so that the wheels do not rotate. Lengthening
the rod causes forward wheel rotation; shortening the rod
causes rearward wheel rotation.
