Leveling the Mower Deck
Check to ensure the mower deck is level any time you install
the mower or when you see an uneven cut on your lawn.
The mower deck must be checked for bent blades prior to
leveling; any bent blades must be removed and replaced. Refer
to the Checking for Bent Blades procedure before continuing.
The mower deck must be leveled side-to-side first then the
front to rear slope can be adjusted.
Requirements:
•
The machine must be on a level surface.
•
All four tires must be properly inflated. Refer to Checking
the Tire Pressure in the Drive System Maintenance
section.
Side-to-Side Leveling
1. Park the machine on a level surface and disengage the
blade control switch.
2. Move the motion control levers outward to the park
position, stop the engine, remove the key, and wait for
all moving parts to stop before leaving the operating
position.
3. Set the height-of-cut lever to middle position.
4. Carefully rotate the blade so that they are all side to
side (Figure 49).

5. Measure between the outside cutting edges and the
flat surface (Figure 49). If both measurements are not
within 5 mm (3/16 inch), an adjustment is required;
continue with this procedure.
6. Support the weight of mower deck by placing wood
blocks under the edges of the deck.
Note: Avoid placing the supports under any anti-scalp
rollers if present on the deck.

7. Move to the left side of the machine. Check if the
side carriage bolt is in the fixed or slotted position
(Figure 50).
8. If the side carriage bolt is in the fixed position, remove
the side carriage bolt and side locking nut from the
fixed position and install it into the slotted adjustment
position (Figure 50).
If the bolt is in the slotted position, the carriage bolt
and side locking nut do not need to be removed.
