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

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.
