Adjusting the Neutral Control
Linkages
Warning
Engine must be running so control linkage
adjustments can be performed. Contact with
moving parts or hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away from rotating parts, muffler and other
hot surfaces.
Warning
Mechanical or hydraulic jacks may fail to support
machine and cause a serious injury.
Use jack stand when supporting machine.
Do not use hydraulic jacks.
1. Disengage the PTO, turn the ignition key to off and
remove the key.
2. Wait for all moving parts to stop before leaving the
operating position.
3. Raise the rear of the machine onto jack stands to raise
the drive wheels off the ground.
4. Start the engine and move the throttle ahead to the full
throttle position.
5. Place the neutral locks in the full forward position and
move the speed control lever to the medium speed
position.
6. Hold OPC levers down.
Note: The OPC levers must be held down whenever the
speed control lever is out of the neutral position or the
engine will kill.
Warning
Electrical system will not perform proper safety
shut off with Operator Presence Control (OPC)
levers held in place.
Make sure Operator Presence Control (OPC)
levers are working when adjustment is
completed.
Never operate this unit with Operator Presence
Control (OPC) levers held in place.
7. Squeeze one drive lever until an increased resistance is
felt. This is where neutral should be.
Note: Make sure you have not reached the end of the
neutral lock slot. If you have, shorten the control lever
linkage. Refer to Adjusting the Control Rod on page 40.
8. If the wheel turns while holding the drive lever in
neutral, the neutral control linkages need to be adjusted
(Fig. 50). If wheel stops then go to step 12.
9. Loosen the nut against the neutral control linkage yoke
(Fig. 50).
10. Adjust the neutral control linkage until the respective
drive wheel stops while the drive lever is pulled against
the neutral spring (neutral position) (Fig. 50).
11. Turn the adjusting bolt approximately 1/4 turn
clockwise if the wheel is turning in reverse or turn the
bolt approximately 1/4 turn counter–clockwise if the
wheel is turning forward (Fig. 50).
12. Release the drive lever to the forward drive position and
squeeze back into the neutral position. Check to see if
the wheel stops. If not, repeat the above adjustment
procedure.
13. After adjustments are made, tighten the nuts against the
yokes.
14. Repeat this procedure for the opposite side.
