Auto-Drive CVT Drive System

Belt control: Double idler tensioner pulleys
The double idler tension pulleys act as a clutch to engage and disengage the drive belt based on the position of
the drive control foot pedal. In addition, when the brake pedal is depressed a bypass rod disengages the idler pulleys
as it engages the brake. It is not possible to engage the drive system when the brake pedal is depressed fully or the
parking brake is engaged. If the tractor creeps when in gear without any input to the drive pedal, the double idler pul
-
ley may be out of adjustment. This condition must be corrected and is covered in the Adjusting The Variable Speed
Control of section of this chapter.
NOTE: The double idler tensioner pulleys can be removed
from the rider without removing the fenders.
NOTE: Confirm that the parking brake is released before
starting work.

bypass rod to the brake pedal assembly rod bracket.
