PARKING BRAKE ADJUSTMENT

WARNING: Never attempt to adjust the brakes
while the engine is running.
If the tractor does not come to a complete stop when
the clutch brake pedal is depressed or the unit rolls
when the parking brake is applied, the brake needs to
be adjusted.
The brake is located on the right side of the transmis-
sion.

assembly. See Figure 11.

SPEED CONTROL ADJUSTMENT

NOTE: When operating the unit initially or after
replacing the belts, there will be little difference
between the highest two speeds until after the
belts have gone through a break-in period and
have seated themselves in the pulleys.
