MANDREL FIG. 22 TO CHECK AND ADJUST BRAKE (See Fig. 23) 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. • 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. • Measure distance between brake operating arm and nut "A" on brake rod. • If distance is other than 1-1/2", loosen jam nut and turn nut "A" until distance becomes 1-1/2". Retighten jam nut against nut "A". • Road test tractor for proper stopping distance as stated above. Readjust if necessary. If stopping distance is still greater than five (5) feet in highest gear, further maintenance is necessary. Replace brake pads or contact a qualified service center. 22
