To determine if it is necessary to adjust the neutral
return, perform the following steps.

1. Disengage the PTO, engage the parking brake and

turn off the engine.

2. Move the ground speed control levers into the operat-

ing position, pull levers rearward and release.

3. Move the ground speed control levers out towards

the neutral position.  If the levers do not align with the
notches in the neutral lock plate, it is necessary to
adjust the neutral return rod (C, Figure 13).

1. Loosen the jam nut (B) locked against the clevis (A).

2. Turn the neutral return rod (C) to adjust handle posi-

tion.

4. Pull lever rearward and release to check position

again.  Adjust as necessary to align levers with
notches.

It is important to note that after every adjustment of the
neutral return rod, the lever must be pulled rearward and
released to properly check the neutral position.

5. Once the lever alignment has been adjusted, lock

jam nut against the clevis.

If the tractor creeps while the ground speed control
levers are locked in neutral, then it may be necessary to
adjust the linkage rods.  

Perform this adjustment on a hard level surface such as
a concrete floor.

IMPORTANT NOTE: This adjustment should be per-
formed with the engine OFF.  Perform the adjustment,
then start the engine to check the adjustment.  If further
adjustment is required, stop the engine before adjusting
the linkage.

1. Determine which wheel is creeping.  The left side

hydro pump and control linkage control the left wheel,
the right linkage controls the right wheel.

2. Disengage the PTO, engage the parking brake, turn

the engine off, remove the key, and wait for all mov-
ing parts to stop.

3. Check the control rod spring (A, Figure 14) length.

The compressed spring length should be 2-3/16”
(5,56cm)

4. Disconnect the rod end (B) and loosen the jam nut.

Turn the rod end one to two turns to lengthen or
shorten the control rod, then retighten the jam nut,
and reconnect the rod end.

5. Start the unit and check for transmission creep.

Repeat steps 2-4 if necessary.
