TO CHECK AND ADJUST BRAKE

(See Fig. 25)
Your tractor is equipped with an ad just able brake system
which is mounted on the right side of the transaxle.
If tractor requires more than fi ve (5) feet to stop at highest
speed in high est gear on a level, dry concrete or paved
surface, then brake must be checked and ad just ed.
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
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.

Depress clutch/brake pedal all the way down and en-
gage parking brake.
