• Never mix oil and gasoline.

NOTE: All gasoline is not the same. If the engine experiences starting or performance problems after using a new gasoline, switch to a different fuel provider or fuel brand.

IMPORTANT: Excessively oxygenated or reformulated fuels (fuels blended with alcohols or ethers) can damage the fuel system or cause performance problems. If any undesirable operating problems occur, use a gasoline with a lower percentage of alcohol or ether.

Fuel Stabilizer

Gasoline left in the fuel system for extended periods without a stabilizer will deteriorate, resulting in gum deposits in the system. These deposits can damage the carburetor and the fuel hoses, filter and tank. Prevent deposits from forming in the fuel system during storage by adding a quality fuel stabilizer to the fuel. Follow the recommended mix ratio found on the fuel stabilizer container.

Moving the anchor point up the lift arm increases the amount of force required to lift the deck.

Anti-scalp Roller Adjustment

The anti-scalp rollers are set at the factory for typical mowing height, but can be adjusted for high or low cutting conditions (Figure 23).

Anti-Scalp rollers are intended to prevent lawn scalping, not to control cutting height.

For a very high cutting height, set the antiscalp rollers in the lowest position on the bracket.

For a very low cutting height, set the antiscalp rollers in the highest position on the bracket.

NOTE: There are four anti-scalp rollers on the outside of the mower deck and four antiscalp rollers on the inside of the mower deck. Make sure all anti-scalp rollers are set at the same height.

Removing the Mower Deck

1. Remove PTO belt (See Replacing Mower Belts on page 29).

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 chains.

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

Lift Assist Adjustment

The list assist springs can be adjusted to provide more assist or to help make the deck more stable. Decreasing the amount of force required to lift the mower deck will increase the mower deck’s bouncing.

Lift assist can be adjusted in two ways: Move the spring anchor to a higher position

on the lift arm to increase the amount of effort required to lift the deck and reduce any bounce in the deck.

Adjust the eyebolt spring anchor on the frame. Making the spring longer decreases the amount of force required to lift the deck.

NOTE: Make sure the lift assist springs are in the same position and are adjusted to the same tension on each side of the deck to prevent cut quality issues.

NOTE: Support the mower deck on blocks or jack stands before disconnecting link chains from mower lift arms to prevent the deck from falling.

2. Raise the deck to the transport position and then disconnect the lift assist springs from the lift arms on each side of the deck.

3. Slowly lower the deck to its lowest position.

4. Remove link chains from mower lift arms.

5. Remove the rear mower mounting pins connecting the mower mounting arms to the deck.

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

7. Turn the blades so the blade ends point front to back as shown in Figure 26.

8. Measure the distance between the ground and the cutting edge of the middle blade at the front of the deck (Front position in Figure 26) and between the ground the cutting edge of the left and right blades at the rear of the deck (Rear position in Figure 26).

9. The cutting edge at the front of the deck (Front position in Figure 26) should be 1/8 in. (3.18 mm) lower than the cutting edges at the rear of the deck (Rear position in Figure 26).

10. If measurements are out of range, raise the low side of the deck using the height adjusters on the deck lift brackets (see Figure 27). Be sure to raise the deck evenly to keep the deck level side to side.

NOTE: 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.

11.Remove the blocks from under the deck.
