TO ADJUST ATTACHMENT CLUTCH

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 a Sears or other qualified service center.

1.Make sure attachment clutch and igni- tion switches are in "OFF" position.

2.Adjust the three nylon Iocknuts until space between clutch plate and rotor measures .012" at all three slot loca-

tions cut in the 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 CHECK AND ADJUST BRAKE

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

1.Park tractor on a level, dry concrete or paved surface, depress clutch/brake pedal all the way down and engage parking brake.

2.Place gear shift lever in neutral (N)

position.

The rear wheels must lock and skid when you try to manually push the tractor for- ward. If the rear wheels rotate, the brake needs to be adjusted or the pads need to be replaced.

TO ADJUST BRAKE

1.Depress clutch/brake pedal all the way down and engage parking brake.

2.Measure distance between brake oper- ating arm and nut "A" on brake rod.

3.If distance is other than 1-3/4", loosen jam nut and turn nut "A" until distance becomes 1-3/4". Retighten jam nut against nut "A".

4.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 neces- sary. Replace brake pads or contact a Sears or other qualified service center.
