Maintenance
Mower Deck Drive Belt
Tension
Self-tensioning - No adjustment necessary.
Park Brake Adjustment
If the parking brake does not hold securely, an
adjustment is required.
1.
Park the machine on a level surface.
2.
Shut off engine and wait for all moving parts to
stop.
3.
When the park brake is released, the brake bars
should lift off the tires and the hand lever should
travel forward. When the brake is disengaged, the
gap between the brake snubber teeth and drive
tire should measure 1/2–5/8 inch (13–16 mm)
(see Figure 28).

1.
Hairpin and washer
3.
1/2–5/8 inch (13–16 mm)
2.
4.69–4.81 inch
(11.9–12.2 cm)
4.
If the parking brake does not hold securely an
adjustment is required. To adjust the brake,
remove and retain the hairpin and washer
on the brake linkage rod. Turn the brake
linkage rod clockwise to decrease the gap
and counterclockwise to increase the gap (see
Figure 28).
5.
Reinstall the rod into the brake lever and secure
with the washer and hairpin.
Motion Control Tracking
Adjustment
Located in the front inside the tower. Rotating the
pump linkage with a 9/16 inch wrench allows fine
tuning adjustments so that the machine does not
move in neutral. Any adjustments should be made
for neutral positioning only.
1.
Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
2.
Start engine. Brake must be engaged and motion
control levers out to start engine. Run engine at
full throttle and release brake.
3.
Run the unit at least 5 minutes with the drive
levers at full forward speed to bring hydraulic oil
up to operating temperature.
Note:
The motion control lever needs to be in
neutral while making any necessary adjustments.
4.
Bring the motion control levers into the neutral
position. Access the links from the front of the
tower (Figure 29). Adjust pump control rod
lengths by loosening the bottom nuts on each and
rotating the turn buckle until the wheels slightly
creep in reverse (Figure 29). Pumps have a return
to neutral arms and will return to neutral when
the control levers are released. If the levers do not
fold out, adjust the links until the lever folds out
in the middle of the neutral lock notch. Move the
levers to the full forward and reverse. If the levers
fold out, tighten the jam nuts on the links.
