Troubleshooting

PTO CLUTCH ADJUSTMENT

Check the PTO clutch adjustment after the initial 25 hour break-in period and then after every 100 hours of operation. Also perform the following procedure if the clutch is slipping or will not engage, or if a new clutch has been installed.

1.Remove key from ignition switch and disconnect spark plug wires to prevent the possibility of accidental starting while the PTO is being adjusted.

2.See Figure 30. Note the position of the 3 adjustment windows (A) in the side of the brake plate and the nylock adjustment nuts (B).

3.Insert a .016”-.018” (0,40-0,45mm) feeler gauge

(C) through each window, positioning the gauge between the rotor face and the armature face as shown in Figure 31.

4.Alternately tighten the adjustment nuts (B, Figure 30) until the rotor face and armature face just contacts the gauge.

5.Check the windows for an equal amount of tension when the gauge is inserted and removed, and make any necessary adjustments by tightening or loosening the adjustment nuts.

NOTE: The actual air gap between the rotor and armature may vary even after performing the adjustment procedure. This is due to dimensional variations on component parts, and is an acceptable condition.

6.Check the mower blade stopping time. The mower blades and mower drive belt should come to a complete stop within seven (7) seconds after the electric PTO switch is turned off.

WARNING

To avoid serious injury, perform adjustments only with engine stopped, key removed and tractor on level ground.

Blade Brake Check

Mower blades and mower drive belt should come to a complete stop within seven (7) seconds after electric PTO switch is turned off.

1.With parking brake engaged, PTO disengaged and an operator in the seat, start the engine.

2.Have an assistant observe the mower drive belt through the open end of the left-hand arbor cover. Engage the PTO and wait several seconds. Disengage the PTO and check the amount of time it takes for the mower drive belt to stop.

3.If the mower drive belt does not stop within seven

(7) seconds, perform the PTO Clutch Adjustment. If the belt still does not stop within seven (7) seconds, see your dealer.
