Scrubber Brake Adjustment - SD
Use "trial and error" to adjust scrubber braking action
and achieve a stopping time of approximately 4 to 5
seconds after disengaging clutch with full throttle. Do
not exceed five (5) seconds. Avoid having the
brake stop too quickly, as this will reduce PTO drive
belt life (burns belt).
Also check for alignment of the brake bar (scrubber)
on the belt and make sure bar is only contacting the
back of belt and not the edges of the pulley(s). For
GHS models, it may be necessary to spring the brake
mount bar to shift (align) the brake bar on the belt;
likewise, the scrubber on SD models is bent for align-
ment with the belt.

Transmission Control

IMPORTANT: The proper adjustment of the trans-
mission control stops is essential for efficient oper-
ation and life of the transmission. These stops are
properly adjusted at the factory and should only re-
quire readjustment if the transmission or related con-
trol linkage is removed or changed.
NOTE: It would not be unusual for a new machine,

after initial 5 or 10 hours of operation, to begin to not
travel straight (this is due to the break-in of the
transmissions). In this case, proceed to Straight
Ground Travel Adjustment - Step 4.

IMPORTANT: The following adjustment procedures
are sequential. Check and adjust each function in
the order given.
Set Forward Travel Limit (Stop) - Step 1
1. Move the Forward Speed Control (FSC) lever to
the most FORWARD position.
2. Check clearance of the RH and LH steering lever
actuator arms with the frame and adjust for-
ward stop bolt so each lever clears the frame
by at least 1/16 in. (1.6 mm). Clearance of the
arm to the frame should be checked while ap-
plying pressure back on the arm to remove any
slack in the linkage.
3. Tighten the jam nut on the forward travel stop ad-
justing bolt.
