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.

•      Place gear shift lever in neutral (N) 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.

nut against nut “A”.

•         Road test tractor for proper stopping distance as stated 

above.  Readjust if nec es sary.  If stopping distance is 
still greater than fi ve (5) feet in high est gear, further
