,A WARNING v

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

PTO CLUTCH ADJUSTMENT

Adjustment of the PTO clutch is usually not necessary on new units.

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 35. Note the position of the 3 adjustment windows (A) in the side of the brake plate, then rotate the pulley so that each of the three rivet joints (visible inside the gap between the pulley and the brake plate) is positioned approximately midway between the three adjustment windows.

3.Insert a .012” feeler gauge through each window, positioning the gauge between the rotor face and the armature face as shown in Figure 36.

4.Alternately tighten the adjustment nuts (B, Figure 35) 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 .Darts. and is an acceotable 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.

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.

2.Look over the left-hand footrest aHhe mower drive belt. Engage the PTO and wait se&al seconds. Disengage the PTO and check the ambunt of time it takes for the mower drive belt to stop.

3.If mower drive belt does not stop within five seconds, perform the PTO Clutch Adjustment. If the belt still does not stop within 5 seconds, see your dealer.
