Checking the Hydro Neutral
Position
No Parts Required
Procedure
Ensure that the neutral position is set properly. If the
tractor moves when the traction control pedal is not
pressed, adjust the neutral position.
1. With the tractor in the Neutral position, run the
engine at a low idle and move the traction control
pedal forward, then release.
2. Move the traction control pedal to reverse, then
release.
If the tractor moves while it is in the Neutral position,
complete the following procedure to adjust it:
1. Run the tractor for 5 to 10 minutes to warm up the
transaxle.
2. Disengage the blade (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Raise the right rear wheel off the ground and support
it with a jack stand.
Note:
Ensure that the left rear wheel stays on the
ground.
Mechanical or hydraulic jacks may fail to
support the tractor and cause a serious injury.
• Use jack stands when supporting the tractor.
• Do not use hydraulic jacks.
Note:
To gain access to the adjusting puck
(Figure 11), you may need to remove the tire.
