SERVICE AND ADJUSTMENTS 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. • Disengage transmission by placing freewheel control in "transmission disengaged" position. Pull freewheel control 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 "transmission engaged" position. • 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. BELT INSTALLATION • Carefully work new belt down onto the input pulley. • Slide belt into the center span keeper. • Pull belt toward front of tractor and roll around the top groove of engine pulley. • Install belt through stationary idler and clutching idler. • Make sure belt is in all pulley grooves and inside all belt guides and keepers. • Install mower (See "TO INSTALL MOWER" in this sec- tion of manual).
