RETURN TO NEUTRAL SETTING
The return to neutral mechanism on the trans-
mission is designed to set the directional con-
trol into a neutral position when the operator
removes their hands from the control. Follow
the procedures below to properly adjust the
return to neutral mechanism on the transaxle:
1. Confirm the transaxle is in the operat-
ing mode (bypass disengaged). Raise the
vehicle’s drive tires off the ground to allow
free rotation.
NOTE: It may be necessary to remove
the drive tire from the axle hub to access
the linkage control and the transaxle
return arm.
2. Remove the Original Equipment Manufac-
turer’s (OEM’s) control linkage at the return
arm. Refer to Figure 5.
3. Start the engine and increase the throttle to
full engine speed.
4. Check for axle rotation. If the axles do not
rotate, go to Step 5. If the axles rotate, go to
Step 6.
5. Stop the vehicle’s engine. Reattach and ad-
just the OEM linkage to the return arm ac-
cording to the OEM manual. Recheck ac-
cording to Step 3 and 4. Stop the vehicle
engine. Refer to Figure 5.
6. Note the axle directional movement. Stop
the vehicle engine. Loosen the lock down
screw until the return arm can be rotated.
Refer to Figure 5 below to make adjust-
ment. In general, rotate the return arm in
the direction opposite of axle rotation. If the
axle is rotating in the “B” direction, rotate
the return arm in the “A” direction, and vice-
versa. Continue until axle rotation stops.
Tighten the lock down screw. Refer to Table
5 Required Torque Values, Page 17. Re-
check according to steps 3 and 4. Stop the
vehicle engine. Reattach and adjust the
OEM linkage according to the OEM manual.
Recheck according to steps 3 and 4. Refer
to Figure 5.
WARNING

cian and/or bystanders, insure the
vehicle is properly secured.
WARNING
Do not attempt any adjustments with the
engine running. Use extreme caution while
inspecting all vehicle linkage!
