5.2MOWER DECK & COMPONENT ADJUSTMENTS 5.2.1. MOWER DECK ADJUSTMENT (LEVELNESS) SIDE to SIDE and FRONT to REAR
Before making deck leveling adjustments, inflate rear tires to 12 PSI and front tires to 25 PSI. When adjust- ed correctly, the deck will be level side to side within 1/8”, have a low cut setting of approximately 1” (1 1/4" for 61 deck) and the blades pitched approximately 3/16” higher at the rear.
1. Place machine on a smooth level surface.
2. Check side to side level by rotating blades until tips are pointing to the sides of the deck. Check the meas- urement of outside blade tips to the ground on both blades. The measurement of each of the outside blade tips should be within 1/8” of each other. If measure- ment of the blade tips is not within 1/8”, adjustment should be made.
3. Set the mower deck to the transport position. Refer to Section “Cutting Height Adjustment”.
4. Relieve tension on deck lift assist spring by loosen- ing nut on eyebolt. Refer to Section “Removing Deck”. 5. Place 1” blocks (1 1/4" for 61 deck) under the front and rear edge of the mower deck.
6. Insert stop pin into lowest cutting height, and lower deck onto blocks.
7. Loosen the top nuts that secure both front deck support eyebolts. Adjust bottom nuts until eyebolts are tight, then retighten top nuts. Torque to 20 to 30 ft. lbs. See Figure 5.5.
