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 alignment with the belt.

Transmission Control

IMPORTANT: The proper adjustment of the transmission control stops is essential for efficient operation and life of the transmission. These stops are properly adjusted at the factory and should only require readjustment if the transmission or related control 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.
