TO CHECK AND ADJUST BRAKE

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 en- gage 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/REPLACE PADS

Contact a qualified service center.

TO ADJUST ATTACHMENT CLUTCH (See Fig. 26)

The electric clutch should provide years of service. The clutch has a built-in brake that stops the pulley within 5 seconds. Eventually, the internal brake will wear which may cause the mower blades to not engage, or, to not stop as required. Adjustments should be made by your nearest authorized service center/department.

•Make sure attachment clutch and ignition switches are in “OFF” position.

•Adjust the three nylon locknuts until space between clutch plate and rotor measures .012" at all three slot locations cut in side of brake plate.

NOTE: After installing a new electric clutch, run tractor at full throttle and engage and disengage electric clutch 10 cycles to wear in clutch plate.

TO REPLACE MOTION DRIVE BELT (See Fig. 27)

Park the tractor on level surface. Engage parking brake. For ease of service there is a belt installation guide decal on bottom of left footrest.

•Remove mower (See “TO REMOVE MOWER” in this section of this manual.)

BELT REMOVAL -

•Create slack in belt by removing retainer spring from drive belt tension handle.

•Remove belt from all idler pulleys, transaxle pulley and then from engine pulley.

BELT INSTALLATION -

•Install new belt around engine pulley first, then around transaxle pulley and lastly into all the idler pulleys.

•Check to be sure belt is positioned correctly and is on proper side of all belt keepers.
