Leveling Mower Deck
CAUTION: Avoid injury! Rotating blades are dangerous.
Before adjusting or servicing mower:
Disconnect spark plug wire(s) or battery negative (-) cable
to prevent engine from starting accidently.
Always wear gloves when handling mower blades or
working near blades.
NOTE: Mower deck anti-scalp wheels should not contact the
ground.
1. Park machine safely. (See Parking Safely in the SAFETY
section.)
2. Inflate tires to the correct pressure.
3. Inspect mower blades for:
• Blade sharpness.
• Blade damage.
• Bent blades.
Checking Level (Side-to-Side)
NOTE: Mower deck anti-scalp wheels should not contact the
ground.
1. Adjust mower deck to 76 mm (3 in.) cutting height position.
NOTE: Discharge chute raised for clarity.
MX20139
2. Position right mower blade (A) (discharge side) perpendicular
to direction of travel.
NOTE: Use a short ruler or a leveling gauge to check the mower
blade level.
3. Measure distance (B) from outside blade tip to the ground.
4. Position left mower blade perpendicular to direction of travel.
5. Measure from outside blade tip to the ground.
• The difference between both measurements should be no
greater than 3 mm (1/8 in.).
6. If side-to-side level is not within the tolerance, an adjustment is
necessary.
Adjusting Level (Side-to-Side)
NOTE: When adjusting U-bolts, maintain a minimum clearance of
3 mm (1/8 in.) between mower deck and stop pads.
MX20099
Adjust four U-bolts (C) (two on each side of deck) until deck is
within 3 mm (1/8 in.) of level from side-to-side.
MX20100
1. Loosen jam nuts (D) and adjust nuts (E) on each U-bolt until
side-to side level is reached.
2. Tighten jam nuts (D).
Checking Level (Front-to-Rear)
1. Set height-of-cut (HOC) to the 76 mm (3 in.) cutting height
position.
NOTE: The height of the rear blade tip should be between 3-6 mm
(1/8-1/4 in.) higher than the front blade tip.
MX20122
2. Position right mower blade (F) (discharge side) parallel to the
direction of travel.
3. Measure distance (G) from front blade tip to the ground.
4. Turn blade 180° and measure from rear blade tip to the
ground.
