If the tractor does not come to a complete stop when
the brake pedal is completely depressed, or if the
tractor's rear wheels can roll with the parking brake
applied, the brake is in need of adjustment. The brake
disc can be found on the right side of the transmission
in the rear of the tractor. Adjust if necessary as
follows:
• Looking at the transmission from the right side of
the tractor, locate the compression spring and
brake disc. See Figure 18.
