Maintenance Instructions ADJUSTMENTS66Scrubber Brake Adjustment - GHSScrubber Brake Adjustment - SDUse “trial and error” to adjust scrubber braking actionand achieve a stopping time of approximately 4 to 5seconds after disengaging clutch with full throttle. Donot exceed five (5) seconds. Avoid having thebrake stop too quickly, as this will reduce PTO drivebelt life (burns belt).Also check for alignment of the brake bar (scrubber)on the belt and make sure bar is only contacting theback of belt and not the edges of the pulley(s). ForGHS models, it may be necessary to spring the brakemount 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 ControlIMPORTANT: The proper adjustment of the trans-mission control stops is essential for efficient oper-ation and life of the transmission. These stops areproperly 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 nottravel straight (this is due to the break-in of thetransmissions). In this case, proceed to StraightGround Travel Adjustment - Step 4.IMPORTANT: The following adjustment proceduresare sequential.
