TO ADJUST BRAKE (See Fig. 27)
Your tractor is equipped with an adjustable brake system
which is mounted on the 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 necessary. Contact your nearest au-
thorized service center/department.
