1. Place the transmission in gear and release the park-

ing brake.

ward. There should be a 1/8" (32 mm) gap between

the lever (A) and the stop (B) as shown.

3. To adjust clearance, turn nut (C) clockwise to

decrease the gap or turn nut counterclockwise to

increase the gap.

4. See Figure 30. Set the parking brake. Loosen or

tighten adjustment nut (C) to achieve a 2-1/2” to 2-

5/8” (6.35 cm to 6.67 cm) compressed spring length

MOWER ADJUSTMENTS

PTO Clutch Adjustment

The PTO clutch adjustment should be checked when a

new belt is installed or if the mower belt is slipping.

1. Install the mower deck on the tractor (the mower

shown in Figure 31 was removed for clarity).

2. Stop the engine, remove the key, set the parking

brake, and disconnect the spark plug wire(s).

3. Disengage the PTO lever.

4. Loosen the set collar (B).

5. Pull the clutch rod back until the cotter pin (C) con-

tacts the U-shaped bracket (D). Slide the set collar

(B) forward to remove all slack from the clutch rod

and spring assembly. The collar should be touching

the spring, but not compressing it.

6. Tighten the set collar (B).

7. Engage the PTO lever.

8. Measure the length of the compressed clutch spring

(A). The spring should be 2-7/8” to 3” (7.3 cm to 7.62

cm) when compressed. If the spring is not within this

range, proceed to the next step.

9. Disengage the PTO. Loosen the set collar and move

the cotter pin (C) to the middle or outermost hole in

the clutch rod.

10. Repeat steps 5-8.
