Check the parking brake for proper adjustment.
Important It is necessary to adjust and check the
proper function of the brake due to the added weight of
the bagger to the unit.
1. Disengage the brake lever (lever down).
2. Measure the length of the spring. The measurement
should be 2–5/8 inch (67 mm) between the washers
(Fig. 41).
