Neutral Adjustment & Tracking Adjustment
If the unit "creeps" while the forward speed control lever is in
the neutral position, then it may be necessary to adjust the
adjustment linkage rods.
The illustration depicts the left side of the machine.
Neutral Adjustment
1.
Park the mower on a flat level surface such as a concrete
floor, away from bystanders and preferably facing a wall.
Disengage the PTO, engage the parking brake, turn the
ignition switch to OFF and remove the key.
2.
Chock the front caster wheels. Raise the drive wheels off
the ground and secure the mower with jack stands.
3.
Start the engine and adjust the throttle control to the SLOW
position. See
Starting the Engine section for proper starting
instructions.
4.
Loosen the jam nuts (A, Figure 20) that are tightened
against the ball joints (B).

5.
Disengage the parking brake.
6.
Slowly turn the adjustment linkage rod (C) clockwise until
the drive tire begins to rotate backwards.
7.
Slowly turn the adjustment linkage rod counter-clockwise
until the drive tire begins to rotate forward.
8.
Set the adjustment halfway in between where the forward
and backwards rotations begin.
9.
Re-tighten the jam nuts.
10. Perform this adjustment for the other side of the mower.
11. Adjust the throttle control to FULL (highest setting). Cycle
the forward speed control lever and the neutral return pedals
several times to insure an accurate adjustment has been
made.
• If the mower still creeps, perform the adjustment
procedure again.
• If the mower does not creep, no further neutral
adjustments are necessary.
Tracking Adjustment
Before making a tracking adjustment, be sure to check the
following:
• Drive tires are properly inflated.
• Caster tires are lubricated and turn freely.
• All controls are free from damage and operate freely.
• Machine is at full operating temperature.
• Make sure the machine is in neutral when the foot pedal is
depressed. If not, adjust neutral as described above.
If machine veers to the LEFT:
1.
Loosen the jam nuts (A, Figure 20) that are tightened
against the ball joints (B).
2.
Turn the LEFT adjustment linkage rod 1/8 - 1/4 turn
counter-clockwise.
3.
Turn the RIGHT adjustment linkage rod 1/8 - 1/4 turn
clockwise.
4.
Re-tighten the jam nut.
5.
Drive machine on a flat, level surface to test and repeat
steps 1 - 4 as necessary.
If machine veers to the RIGHT:
1.
Loosen the jam nuts (A, Figure 20) that are tightened
against the ball joints (B).
2.
Turn the RIGHT adjustment linkage rod 1/8 - 1/4 turn
counter-clockwise.
3.
Turn the LEFT adjustment linkage rod 1/8 - 1/4 turn
clockwise.
4.
Re-tighten the jam nut.
5.
Drive machine on a flat, level surface to test and repeat
steps 1 - 4 as necessary.
Drive Levers - Control Responsiveness
Adjustment
This mower is equipped with drive lever spring assemblies (A,
Figure 21) that control the level of responsiveness of the controls
to the transmissions. The drive levers (B) are factory preset for
normal operation. The spring assemblies can be adjusted
equally to improve the responsiveness of the drive levers under
more adverse operating conditions.
The drive lever spring assemblies have a range of adjustment
(C) from the factory preset position of 7-1/4" (18.4 cm) to the
maximum position of 6-1/2" (16.5 cm). These measurements
are taken by measuring the length of the spring (D).
