Figure 19. Deck Level Adjustment
Check & Level the
Mower Deck
NOTE: Before adjusting the deck level, the deck lift rod
timing must be checked and adjusted if necessary.
1. Park machine on a flat, level surface 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. Install the cutting height adjustment pin in the
4” (10,2 cm) position. See Figure 20.
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” (0,64 cm) thick spacer on top of the rear 2 x 4
blocks. See Figure 18.
4. 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 19.
5. 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 in the slots until the chains are tight and
tighten the nuts. See Figure 19.
6. Remove all 2 x 4 blocks and spacers from under the
mower deck.
7. For your safety, DO NOT handle mower blades
with bare hands. Position the outside mower
blades so that they face front-to-back (Figure 21).
8. Measure from the front tip of the blade from the
cutting edge to the ground. Measure from the rear
tip of the blade from the cutting edge to the ground.
Repeat this process for the other side of the
machine. The front measurements should be 4”
(10,2 cm), the back measurements should be 4-1/4”
(10,8 cm). If the measurements are greater than
1/8” (3,17 mm) of what they should be adjust the
deck height until they are correct.
