Your tractor is equipped with an adjustable brake system

high speed in highest gear on a level dry concrete or paved
surface, then brake must be adjusted.

Depress clutch/brake pedal and engage parking brake.
• Measure distance between brake operating arm and nut

• If distance is other than 1-3/4", loosen jam nut and turn
nut “A” until distance becomes 1-3/4". 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 necessary. Contact your nearest au-
thorized service center/department.
