Blade Brake Band Adjustment - Step 3
After the pulley travel is set, make the following
adjustment as needed:
1. Adjust the blade brake band, using the adjust-
ment nut until there is a gap of approximately
1/8 in. (3 mm) between the PTO belt tightener
stop block and chassis. If there are not
enough threads on the brake band for adjust-
ment, lengthen the brake actuator rod.
