Maintenance
Fine Adjustment Procedure
1. Loosen the jam nut (A, Figure 45) and turn the fine
adjustment bolt (B) to adjust the deck height until the
front measurement equals 4" (10,2 cm) and the back
measurement equals 4" (10,2 cm)
• Turn the bolt CLOCKWISE to raise the deck.
• Turn the bolt COUNTER-CLOCKWISE to lower the
deck.
2. Position the outside mower blades so that they face
front-to-back.
3. Re-measure from the front tip of the blade from the
cutting edge to the ground. Measure from the rear tip of
the blade from the cutting edge to the ground. Repeat
the process for the other side of the machine.
3. Once the front measurement equals 4" (10,2 cm) and the
back measurement equals 4" (10,2 cm), re-tighten the
jam nut.

PTO Clutch Belt Replacement

1. Park the tractor on a smooth, level surface such as a
concrete floor. Disengage the PTO, engage the parking
brake, turn off the engine, and remove the ignition key.
2. Raise the hood to gain access to the PTO clutch belts (A,
Figure 46) located on the rear of the engine.
3. Remove the PTO clutch anchor bolt (B).
4. Using a 1/2" breaker bar, place the square end in the
square hole located in the end of the idler arm (C).
Carefully rotate the breaker bar CLOCKWISE, which will
relieve the tension on the belts exerted from the idler
arm.
5. Slide the PTO clutch belts over the edge of the drive
shaft pulley (D). Carefully release the tension on the
breaker bar.
6. Remove the old PTO clutch belts and replace with new
ones. Make sure the V-side of the belts runs in the
pulley grooves.
7. Install the new PTO clutch belts on the PTO clutch (E)
and the idler pulley (F). Carefully rotate the breaker bar
CLOCKWISE and install the belt on the drive shaft pulley.
Carefully release the tension on the breaker bar.
8. Re-install the PTO clutch anchor bolt.
9. Close the hood and secure with the hood latches.
10. Run the mower under no-load condition for about 5
minutes to break-in the new belt.
