5. Measure between the outside cutting
edges and the flat surface (Figure 41). If
both measurem ents are not within
3/16 inch (5mm), an ad justment is
required; continue with this procedure.
6. Check the front-to-rear blade level any
time you install the mower. If the front
blade tip is not 1/16-5/16 inch
(1.6-7.9 mm) lower than the rear blade tip,
adjust the blade level. If measurements
from step 5 or 6 are out of range, then
follow Adjusting the Blade Slope.
7. Set anti-scalp rollers to top holes or
remove completely for this adjustment.
8. Set the height-of-cut lever to the 3 inch
(76 mm) position. Place two 2 1/2”
(6.35 cm ) thick blocks under the rear edge
of the cutting deck skirt; one on each side
of the cutting deck. Place two 2 5/16”
(5.89 cm ) blocks unde r each side of the
front edge of the deck, but no t under the
anti-scalp roller brackets.
9. Carefully rotate the blades side to side
(Figure 41 ).

10. Loosen the leveling adjust locking nuts
(item 3) on all four corners so that the
deck is sitting securely on all four blocks.
Make sure that the deck hangers are all
the way down (at the top of the slot) and
the deck lift foot lever is pushed back
against the stop, then tighten the four
leveling adjust locking nuts (Figure 42).
11. Recheck that blocks fit just snugly under
the deck skirt. Make sure all attachment
bolts are tight.
12. Continue leveling the deck by checking
the front- to- rear blade slope; refe r to
Adjusting the Front-to-Rear Blade Slope.
13. Recheck blades for levelness and repeat
deck leveling procedure if necessary.

Adjusting the Blade Slope
1. Check the front-to-rear blade level any
time you install the mower. If the front
blade tip is not 1/16-5/16 inch
(1.6-7.9 mm) lower than the rear blade tip,
adjust the blade level using the following
instructions:
2. Park the machine on a level surface and
disengage the blade control switch.
3. Move the motion control levers outward to
the neutral position, engage the parking
brake, stop the engine, remove the key,
and wait for all moving parts to stop
before leaving the operating position.
4. Check the air pressure of all four tires . If
needed, adjust to the recommended
inflation; refe r to Checkin g the Tire
Pressure in Drive System Maintenance.
5. Check and adjust the side-to-side blade
level if you have not checked the settin g ;
refer to Leveling the Mower from Side-to-
Side.
