Determining if the Deck Leveling Needs to be
Adjusted
1. Park the unit on a flat, level surface. Disengage the PTO,
engage the parking brake, turn the ignition switch to OFF,
and remove the ignition key.
2. Lock the deck lift pedal in the TRANSPORT position.
Place the cutting height adjustment pin in the 4" position
and lower the deck lift pedal until the deck lift arm
contacts the cutting height adjustment pin.
3. Verify that the tires are inflated to the correct pressure.
4. Verify that the mower blades are flat, and not bent or
broken. A bent or broken blade must be replaced.
WARNING
Avoid Injury! Mower blades are sharp.
Always wear gloves when handling blades or working near
blades.
5. See Figure 54. Position the outside mower blades so they
face front-to-back.

6. Measure the front tip (A, Figure 54) of the blade from the
cutting edge to the ground.
7. Measure the rear tip (A) of the blade from the cutting
edge to the ground.
8. Repeat the process on the other side of the machine.
• the front measurements should equal 4" (10,2 cm).
• the rear measurements should equal 4-1/4" (10,8 cm)
If the measurements do not equal the measurements as
listed above, adjust the deck leveling.
Deck Leveling Adjustment
1. Set the mower deck to the 4" (10,2 cm) cutting height
position.
2. Measure from the front tips of the blades to the ground.
• If the measurements between the front tips of the
blades and the ground is greater than 4-1/4" (10,8
cm) or less than 3-3/4" (9,5 cm) the mounting
hardware will be to be positioned into different holes.
• If the measurements between the front tips of the
blades and the ground falls between 3-3/4 (9,5 cm)
and 4-1/4" (10,8 cm), skip to step #6.
3. Place blocking underneath all four corners of the mower
deck until the hanger chains are slack.
4. Position the hardware (A, Figure 55) that secures the
front hanger chain (B) to the front mounting plate (C).
• If the measurement between the front tip of the
blade and the ground was 4-1/4" (10,8 cm) or higher,
position the hardware in the next higher hole in the
front mounting plate.
• If the measurement between the front tip of the
blade and the ground was 3-3/4" (9,5 cm) or lower,
position the hardware in the next lower hole in the
front mounting plate.

5. Repeat step #4 for the other side of the deck.
6. Remove the blocking from underneath the deck and
replace with 2 X 4 blocks (B, Figure 56) under each
corner of the mower deck with the 3-1/2" (8,9 cm) sides
being vertical. Place a 1/4" (0,64 cm) thick spacer (C) on
the top of the rear blocks. The arrow (A) points towards
the front of the mower deck.

7. Check the measurements between the front tips of the
mower blades and the ground.
