(Figure 38) The deck lift assist springs are adjusted to

reduce lift effort or to increase deck stability. To adjust the force required to lift the deck:

1. Loosen the jam nut (1) on the lift assist spring anchor bolt.

2. Adjust the spring anchor to the desired setting:

• Loosen the spring anchor (turn counter-

clockwise) to decrease spring tension and increase the effort required to raise and lower the deck. This will also add stability to the deck.

• Tighten the spring anchor (turn

clockwise) to increase spring tension and decrease the effort required to raise and lower the deck.

IMPORTANT: Excessive spring tension will make the deck more likely to lift and bounce off the turf when the mower travels over rough terrain.

3. Repeat for the other side of the deck.

4. Measure the distances between the end of the assist springs and the trunnions on both sides. Ensure that both assist springs are adjusted to the same dimension.

NOTICE: Lift springs must be adjusted to the same tension on each side of the deck to prevent cut quality issues.

Removing the Mower Deck

(Figure 39)

1. Remove PTO belt (See Replacing Mower Belts on page 38).

WARNING: AVOID INJURY. Mower lift arms and mower lift pedal could cause severe injury if the lift assist spring is not disconnected before disconnecting the lift links.

Springs store energy. Keep body parts well away from pinch points when removing the deck.

NOTICE: Support the mower deck on blocks or jack stands before disconnecting links from mower lift arms to prevent the deck from falling.

2. Raise the deck to the transport position and disconnect the lift assist springs (6) from the mower lift arms (1) on each side of the deck.

3. Slowly lower the deck to its lowest position.

6. Level mower deck (See Leveling the Mower Deck on page 42).

Leveling the Mower Deck

These adjustments should be made on a level surface with the tires inflated to the correct air pressure.

Check Blade Level and Pitch

1. Raise mower deck to a 8.9 cm (3 1/2”) cutting height.

2. Shut off engine. Engage parking brake. Remove the ignition key.

3. Turn the blades so the blade ends point left to right across the width of the deck.

4. Measure the distance between the ground and cutting edge of the blade on the left blade (Left position in Figure 40) and on the right blade (Right position in Figure 40). Distances should be within

4.7 mm (3/16”). If they are not, raise the low side of the deck using the height adjusters on the deck lift brackets (see Figure 41).

5. After deck is level side to side, check the deck front to back pitch.

6. Turn the blades so the blade ends point front to back as shown in Figure 40.

7. Measure the distance between the ground and the cutting edge of the middle blade at the front of the deck (Front position in Figure 40) and between the ground the cutting edge of the left and right blades at the rear of the deck (Rear position in Figure 40).

8. The cutting edge at the front of the deck (Front position in Figure 40) should be

3.2 mm (1/8”) lower than the cutting edges at the rear of the deck (Rear position in Figure 40).

9. If measurements are out of range, raise the low side of the deck using the height adjusters on the deck lift brackets (see Figure 41). Be sure to raise the deck evenly to keep the deck level side to side.

NOTICE: Pitching the front of the blades lower than the rear provides a balance between cut quality and the power needed to cut grass. Certain cutting conditions require the deck to be pitched with the rear of the blades lower than the front. Heeling the deck this way requires more engine power but can provide better cut quality.

CLUTCH ADJUSTMENT

(Figure 42) If clutch fails to engage or disengage properly

or begins to make abnormal noise, check the air gap adjustment at the three inspection slots.

To check:

1. Stop engine, remove key and wait for all hot parts to cool.

2. Measure the air gap between the armature and the rotor.

• Minimum: A 0.040 cm (0.016") feeler gauge should slide between armature and rotor with slight contact.

• Maximum: A 0.050 cm (0.020") feeler gauge should slide between armature and rotor with slight contact.

3. Repeat for each inspection slot.

To adjust:

1. If necessary, loosen gap adjustment nuts until a 0.040 cm (0.016") feeler gauge fits between armature and rotor.

2. Slide a 0.050 cm (0.020") feeler gauge between armature and rotor.

3. Tighten gap adjustment nut until there is slight contact on feeler gauge.

4. Repeat steps 1 – 3 at each inspection slot.

NOTICE: Adjust air gap as evenly as possible.

5. Start unit, engage and disengage PTO.

6. Shut off unit.

7. Recheck air gap and adjust if needed.
