TO CHECK AND ADJUST BRAKE (See Fig.
22)
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 engage
parking brake.
• Disengage transmission by placing freewheel control in
“transmission disengaged” position. Pull freewheel con-
trol 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.
