5.2MOWER DECK & COMPONENT ADJUSTMENTS The leveling procedures for the 61 deck differ from the 48 and 52 decks. The 61 deck replaces the two rear eyebolts with slotted brackets, and uses 1 1/4” leveling blocks in place of the 1” blocks. Follow and complete each step carefully.
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 adjusted 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 measurement 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 measurement of the blade tips is not within 1/8”, adjustment should be made.
3. Move deck lift lever and set the mower deck to the highest cutting position.
4. Relive tension on deck lift assist spring by loosening 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. Move deck lift lever and set the mower deck to the lowest cutting position.
6. Loosen the nuts and bolts that secure both front deck support chains. Adjust chains until tight and retighten bolts and nuts. Torque to 70 ft. lbs. See Figure 5.5.
