Hydro-Gear 0500 / 0650 Models
If the tractor creeps forward or backward with the engine
running and both travel pedals released, perform the fol-
lowing adjustment:
NOTE: For Hydro-Gear 0500 transmission part number
1713761 see Figure 8. For the Hydro-Gear 0650 trans-
mission part number 1715765 see Figure 9. An identifi-
cation 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
jack-stands 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 adjustment
rod (B). Move the rod until neutral is found, then
retighten the nut.
NOTE: The stop pin (D, Figures 8 and 9) should be posi-
tioned near the end of the cam slot when the front pedal
edge is 1/4" above the frame (pedal fully depressed,
Figure 13). 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.
