3 ADJUSTMENTS
GB-10
3.7 TRACTION PEDAL NEUTRAL ________________________________________________
1. If the tractor “creeps” in either direction when the
engine is running but the traction pedal is not
depressed, adjust spring tension so that the pedal
always returns to neutral when released.
Note: The tractor may “creep” when the hydraulic oil
is cold. Operate the tractor for 15 minutes before
determining if adjustment is required.
2. Use extreme caution when making this adjustment
as the wheels will be off the ground and the engine
will be running.
3. Engage parking brake, stop the engine, open hoods
then lubricate all linkage pivot points.
4. Chock the rear wheel, and place the front of the
tractor on jackstands.
5. Loosen all nuts ( N ) and adjust rear spring to
position traction arm in neutral.
a. Lock rear nuts and adjust front nuts ( N ) to
maintain 3/8 in. (9 mm) of extension in spring
(
O ).
b. Start the engine and check for “creep” then
repeat the process if necessary.
