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.
See Figure 45.
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 46.
5. Loosen the nuts and allow the rear of the deck to
rest on the 2 x 4's. Slide the chains down in the
slots until the chains are tight and tighten the nuts.
See Figure 46.
6. Remove all 2 x 4 blocks from under the mower
deck.
CAUTION
Avoid injury! Mower blades are sharp.
Always wear gloves when handling blades or
working near blades.
7. See Figure 47. Position the outside mower blades
so they face front-to-back.
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. The measurement should be 4" (10,2
cm). Repeat this process for the other side of the
machine.
