DECK LEVELING ADJUSTMENT

NOTE: Before adjusting the deck level, the deck lift rod timing must be checked and/or adjusted.

1.Park machine on a flat, level surface. Disengage the PTO, stop the engine and engage the parking brake. Rear tires must be inflated to 15 psi (1,03 bar); front tires to 25 psi (1,72 bar).

2.Lock the deck lift pedal in the 5” (12,7cm) position. Place the deck height adjustment pin in the 4" position and lower deck the lift pedal until the arm contacts the pin.

3.Place 2 x 4 blocks under each corner of the mower deck with the 3-1/2” sides being vertical. Place a 1/4” (0,64cm) thick spacer on top of the rear 2 x 4 blocks. See Figure 41.

6.Adjust the front eyebolts until the chains are tight and the deck is still resting on the 2 x 4’s. Tighten jam nuts. See Figure 42.

7.Loosen the nuts and allow the rear of the deck to rest on the 2 x 4’s and 1/4” spacers. Slide the chains down in the slots until the chains are tight and tighten the nuts. See Figure 42.

8.Remove all 2 x 4 blocks and spacers from under the mower deck.
