TO ADJUST BRAKE
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 high-
est gear, then brake must be adjusted.
• Depress clutch/brake pedal and engage
parking brake.
• Measure distance between brake oper-
ating arm and nut "A" on brake rod.
• If distance is other than 1-9/16", loosen
jam nut and turn nut "A" until distance
becomes 1-9/16". 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 authorized ser-
vice center/department.
