TO CHECK AND ADJUST BRAKE   

(See Fig. 20)

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 freewhel 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.

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 

“trans mis sion engaged” position.

•         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 
main te nance is nec es sary.  Replace brake pads or 
contact a qualifi ed service center.
