4.2.5.MOWER DECK ADJUSTMENT (LEVELNESS) SIDE-To-SIDE (48” Decks)

Before making deck leveling adjustments, check the tire pressure. Check tires and add or release air as needed to bring pressure to 12 PSI in front and 12 PSI in rear tires. If tires are properly inflated and mowing is still uneven, adjust side-to-side deck levelness as follows:

1.Place machine on a smooth level surface.

2.Rotate outside blades so tips are pointed to the sides of deck. See Figure 4.5. Measure the distance from blade tips to floor. If the measurement is within 1/8” from side-to-side, the deck levelness is satisfactory. If the difference from side-to-side is greater than 1/8”, continue to next step for adjustment.

3.Place a 2 x 4 piece of wood under the front middle portion of deck. Place one 2 x 4 piece of wood under the rear of deck on both sides behind the two outside blades. See Figure 4.5.

4.Lower deck down to rest on the three 2 x 4 pieces of wood. Make sure there is no deck tension on the lift rods supporting the deck.

5.Loosen the bolt and nut that secures the front lift arm weldment to the front lift arm. See Figure 4.6.
