Section 4 - ADJUSTMENTS & REPAIR

WARNING

DO NOT attempt any adjustments, maintenance, service or repairs with the engine running. STOP engine. STOP blade. Engage parking brake. Remove key. Remove spark plug wire from spark plug and secure away from plug. Engine and components are HOT. Avoid serious burns, allow all parts to cool before working on machine. Fuel Filler Cap and vent must be closed securely to prevent fuel spillage.

4.2.2.MOWER DECK ADJUSTMENT (Side-To-Side Levelness)

Before making deck leveling adjustments, check the tire pressure. Front tires 12 PSI, rear tires 12 PSI. If tires are properly inflated and mowing is still uneven, adjust side-to-side deck levelness.

1.Place Rider on a smooth level surface.

2.Turn engine off and remove key, remove spark plug wire from spark plug and secure wire away from plug.

3.Place a piece of angle iron, pipe, or similar object under center of deck at the rear.

4.Remove rear hanger chains and allow center, rear of deck to rest on angle iron.

5.Measure the distance from blade tips to floor. If the measurement is within 1/8” from side-to-side, the deck attitude is satisfactory. If difference from side-to-side is greater than 1/8”, continue with adjustment.

6.Loosen the shoulder bolt & nut that retains the left side of blade pedal. See Figure 4.3.

8.Tighten shoulder bolt & nut loosened in Step 6. Recheck both sides of deck for correct levelness.

9.Readjust rear hanger chain pivots to align with holes in support brackets.

See Figure 4.4.

10.Remove angle iron, pipe, or similar object and proceed to check front to rear levelness.

4.2.3. MOWER DECK ADJUSTMENT

(Front to Rear Levelness - 28”, & 33” Decks)

With the Rear Engine Rider on a smooth, level surface, rotate blade until blade tips are at front and rear of deck. Measure the distance from blade tips to floor. The distance should be the same, or the rear 1/8” to 1/4” lower than the front. If the rear blade tip is higher or is more than 1/4” lower than the front, proceed with adjustment. Go to Step 1.

(Front to Rear Levelness - 30” Decks)

With the Rear Engine Rider on a smooth, level surface, rotate blade until blade tips are at front and rear of deck. Measure the distance from blade tips to floor. The distance should be the same, or the rear 1/8” to 1/4” higher than the front. If the rear blade tip is lower or is more than 1/4” higher than the front, proceed with adjustment. Go to Step 1.

1.Remove rear hanger chains.

2.Turn each hanger pivot the same number of rotations on the eye-bolt to raise or lower the rear of the deck. See Figure 4.4.

3.Reinstall rear hanger chains and measure blade tips again.

4.Repeat steps “1” through "3” until proper levelness is obtained.
