3.Repeat ten times to burnish the clutch.

WARNING

The muffler and surrounding areas can be extremely hot. Allow the engine to cool before performing this procedure.

1.Remove the tractor hood by disconnecting the head- light coupler and then removing two hinge hooks.

2.Use a 0.015” feeler gauge to check front clutch at three slots (A, Figure 39). There should be a slight resistance as gauge is moved in and out of slot. If tight or loose, proceed to step 3.

3.Loosen or tighten one of the nuts (B, Figure 39) to achieve slight drag on feeler gauge. Check the other two slots and adjust accordingly.

NOTE: Adjustment at one location will change adjust- ment at the two other slots. Make sure all three locations have proper adjustment.

4.With tractor in neutral, PTO disengaged and operator in seat, start the tractor engine.

5.Engage the front PTO and wait several seconds. Disengage the front PTO and check the amount of time it takes for the mower drive belt to stop.

6.If mower drive belt does not stop within five seconds, repeat steps 1-3. If the belt still does not stop within 5 seconds, see your dealer.

BRAKE LINKAGE ADJUSTMENT

1.Turn off the engine and remove the key from the igni- tion. DO NOT engage the parking brake.

2.Remove the back bumper to gain access to the brake rod adjustment nut (A, Figure 40).

3.Angle the brake assembly arm so that is standing straight up. Hold in place.

4.With the brake assembly arm straight up and the brake pedal at rest, turn the brake rod adjustment nut (A, Figure 40) until the spacer (C) contacts the brake pivot arm (D). Do not over-tighten. Over-tightening will cause the brake to drag.
