SERVICE AND ADJUSTMENTS
TO CHECK AND ADJUST BRAKE
(See Fig. 25)
Your tractor is equipped with an adjustable brake system
which is mounted on the right side of the transaxle.
If tractor requires more than five (5) feet to stop at highest
speed in highest gear on a level, dry concrete or paved
surface, then brake must be checked and adjusted.
TO CHECK BRAKE
• Park tractor on a level, dry concrete or paved surface,
depress clutch/brake pedal all the way down and en-
gage parking brake.
• Disengage transmission by placing freewheel control
in "transmission disengaged" position. Pull freewheel
control out and into the slot and release so it is held in
the disengaged position.
The rear wheels must lock and skid when you try to manually
push the tractor forward. If the rear wheels rotate, the brake
needs to be adjusted or the pads need to be replaced.
TO ADJUST BRAKE
• Depress clutch/brake pedal all the way down and en-
gage parking brake.
• Measure distance between brake operating 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".
• Engage transmission by placing freewheel control in
"transmission engaged" position.
• Road test tractor for proper stopping distance as stated
above. Readjust if necessary. If stopping distance is
still greater than five (5) feet in highest gear, further
maintenance is necessary. Replace brake pads or
contact a qualified service center.
