2. Install the blade stiffener, the curved washer (cupped

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 tire 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 50).

5. Measure between the outside cutting edges and the
flat surface (Figure 50 ). If both measurements
are not within 3/16 inch (5 mm), 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. Remove the
side carriage bolt and locking nut from the fixed
position and install it into the rear, slotted position
and leave it slightly loose (Figure 51).
