TO ADJUST BRAKE
Your tractor is equipped with an adjust-
able brake system which is mounted on
the right side of the transaxle.
If tractor requires more than six (6) feet
stopping distance at high speed in
highest gear, then brake must be
adjusted.
• Depress clutch/brake pedal and
engage parking brake.
• Measure distance between brake
operating arm and nut "A" on brake
rod.
• If distance is other than 1-1/2", loosen
jam nut and turn nut "A" until distance
becomes 1-1/2". Retighten jam nut
against nut "A".
• Road test tractor for proper stopping
distance as stated above. Readjust if
necessary. If stopping distance is still
greater than six (6) feet in highest
gear, further maintenance is neces-
sary. Contact your nearest authorized
service center/department.
