Deck Leveling Adjustment
Before adjusting the deck level, the deck lift rod timing must
be checked and/or adjusted.
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 67. Position the outside mower blades so they
face front-to-back.
67
6. Measure the front tip (A, Figure 67) 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 Procedure
1. Place the deck height adjustment pin in the 4" (10,2 cm)
position.
2. Loosen the jam nut (A, Figure 68) on the deck linkages
(B).

3. Turn the hex adjusters on the deck linkages (C)
clockwise to raise the mower deck or counter-
clockwise to lower the mower deck.
Note: If you are lowering the mower deck measure the
amount of visible threads (D) on the deck linkages. If the
amount of visible threads shown reaches 2" (5,1 cm) for the
front linkages or 1-1/2" (3,8 cm) for the rear linkages, do
not lower the mower deck by adjusting the deck linkage any
further.
4. Re-check the measurements from the tips of the mower
blades to the ground. The front measurements should
equal 4" (10,2 cm) and the rear measurements should
equal 4-1/4" (10,8 cm).
• if the measurements are correct, tighten the jam nuts
on the deck linkages. The adjustment procedure is
complete.
• If the measurements are not correct, the hole that the
deck linkage is mounted in on the mower deck will
have to be changed.
5. Place blocking underneath all four corners of the mower
deck.
6. Re-position the hardware (A, Figure 69) that secures the
deck linkage to the mower deck.
• If the mower deck was being raised when it was
unable to achieve the correct measurements, position
the hardware in the next lower hole (B) in the mower
deck mount (C).
• If the mower deck was being lowered when it was
unable to achieve the correct measurements, position
the hardware in the next higher hole in the mower
deck mount.
