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.
Leveling the Mower from Side-to-Side
The mower blades must be level from side to side. Check the
side-to-side level any time you install the mower or when you
see an uneven cut on your lawn.
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.
Check the air pressure of all four tires. If needed, adjust
to the recommended inflation; refer to Checking the
Tire Pressure in the Drive System Maintenance section.
4.
Set the height-of-cut lever to the 76 mm (3 inch)
position.
5.
Carefully rotate the blade(s) side to side (Figure 60).
Measure between the outside cutting edges and the
flat surface (Figure 60). If both measurements are not
within 5 mm (3/16 inch), an adjustment is required;
continue with this procedure.

6.
Move to the left side of the machine. Loosen, but do
not remove, the rear locking nut on the hanger bracket
(Figure 61).
7.
Loosen the side locking nut on the hanger bracket
just enough to allow the eccentric plate to be adjusted
(Figure 61). Use a 3/8 inch drive extension on a socket
wrench to manipulate the eccentric plate. Use the
wrench to reposition the height of the mower deck and
adjust it so that the measurements taken in step5 are
within 5 mm (3/16 inch).
8.
Stop the deck at the adjusted position and tighten the
side locking nut on the hanger bracket to hold the new
position (Figure 61). Tighten the rear locking nut on
the hanger bracket.
9.
Continue leveling the deck by checking the front-to-rear
blade slope; refer to Adjusting the Front-to-Rear Blade
Slope.

Adjusting the Front-to-Rear Blade
Slope
Check the front-to-rear blade level any time you install the
mower. If the front of the mower is more than 7.9 mm
(5/16 inch) lower than the rear of the mower, adjust the blade
level using the following instructions:
1.
Park the machine on a level surface and disengage the
blade control switch.
