PTO CLUTCH ADJUSTMENT

Check the PTO clutch adjustment after the initial 25 hour break-in period and then after every 250 hours of opera- tion. 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 acciden- tal starting while the PTO is being adjusted.

2.See Figure 25. 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 26.

4.Alternately tighten the adjustment nuts (B, Figure 25) 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.

WARNING

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

BLADE BRAKE CHECK

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

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

2.Have an assistant observe the mower drive belt through the opening between the frame and top of mower deck. Engage the PTO and wait several sec- onds. 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 five sec- onds, perform the PTO Clutch Adjustment. If the belt still does not stop within 5 seconds, see your dealer.
