If the tractor creeps forward or backward with the

perform the following adjustment:
NOTE: For Hydro-Gear 0500 transmission part
number 1713761 see Figure 7-7. For the Hydro-Gear
0650 transmission part number 1715765 see Figure
7—8. An identification decal is attached to the
transmission case.
1. Block the front wheels and raise the rear of the
tractor off the ground with a suitable hoist or
floor jack. Install jackstands underneath the
transaxle.
2. Start the engine and release the parking brake
while keeping seat switch depressed.
3. Loosen the nut (A) securing the neutral adjust-
ment rod (B). Move the rod until neutral is found,
then retighten the nut.
NOTE: The stop pin (D, Figure 7-7 and 7-8) should
be positioned near the end of the cam slot when the
front pedal edge is 1/4" above the frame (pedal fully
depressed). If it is not, proceed to the Forward
Speed Adjustment procedure. The stop pin should
not “bottom out” in the cam slot. Increasing the
distance between the end of the cam slot and the
stop pin will increase reverse speed and decrease
forward speed.
