CHECK / ADJUST PTO CLUTCH

•ILWARNING

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

level ground.

Service interval: 200 Hours.

The PTO clutch is engaged and disengaged by the PTO switch. The clutch powers and brakes the mower blades. Check the PTO clutch adjustment every 200 hours of operation. Also perform the following procedure if the clutch is slipping, 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 acciden- tal starting while the PTO is being adjusted.

2.See Figure 22. 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 .012"-.015"(2,5-4mm) feeler gauge (C) through each window, positioning the gauge between the rotor face and the armature face as shown in

Figure 23.

4.Alternately tighten the adjustment nuts (B, Figure 22) 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 loosen- ing the adjustment nuts.

NOTE: The actual air gap between the rotor and arma- ture may vary even after performing the adjustment pro- cedure. This is due to dimensional variations on compo- nent parts, and is an acceptable condition.

6.Check the mower blade stopping time. The mower blades and mower drive belt should come to a com-

plete stop within five seconds after the electric PTO switch is turned off. If adjustment does not stop a mower braking problem, replace the electric PTO clutch.
