TRACTION PEDAL NEUTRAL ________________________________________________

1. If the mower "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 mower may "creep" when the hydraulic oil
is cold. Operate the mower 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
mower on jackstands.
5. Loosen all nuts (N) and adjust rear spring to
position traction arm in neutral.
9.8

TRACTION PEDAL FORWARD STOP __________________________________________

Loosen nuts (P) move the traction pedal to its maximum
forward position. Adjust screw (Q) until the head just
touches the traction pedal arm. Return traction pedal to
neutral and turn screw (Q) out one full turn. Tighten nuts
(P).
Important: Screw (Q) must stop traction pedal before the
internal stops in the hydrostatic transmission are
contacted.
9.9

LIFT / LOWER PEDAL STOP _________________________________________________

Adjust bolts (R and S) to stop spool valve from hitting the
internal stops, while maintaining the full stroke of the
spool.
ADJUSTMENTS

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.
