MAINTENANCE
LEVELING THE CUTTING DECK
See Figures 23 - 24.
If your lawn appears unevenly cut after using the mower,
the cutting deck may need adjusting. Before deciding that
leveling the cutting deck is necessary, make sure tires are
properly inflated to the recommended PSI when mowing.
Over- or under-inflated tires can affect the appearance of
the cut, and proper inflation of the tires may be all that is
needed to resolve uneven cutting issues.
NOTE: Always check side-to-side alignment and adjust as
needed before measuring and adjusting front to back.
Before beginning:
Make sure drive levers are in open position and blade
engage knob is down.
Stop the motor, allow the blades to come to a complete
stop, remove the start key, and set the parking brake.
Raise the height of the cutting deck to its highest position.
To make side-to-side adjustment:
Position the blades so that the ends point toward the
sides of the mower.
On the outside edge of each blade, measure the distance
from the bottom edge of the side of the blade to the
ground. If the distance between the two sides is greater
than 1/8 in., a side-to-side adjustment is necessary.
On the side you wish to adjust, loosen the jam nuts as
shown.
Turn the adjustment nuts clockwise to raise or counter-
clockwise to lower the side of the cutting deck. Each full
turn of the adjustment nut will change the deck height
approximately 3/16 in.
NOTE: If raising the side, you will need to turn the top
adjustment nut first. If lowering, turn the bottom nut first.
Measure again. Continue to adjust and measure until the
difference between the distance on each side is 1/8 in.
or less.
Proceed to front-to-back adjustment or retighten jam nuts
to secure.
To make front-to-back adjustment:
NOTE: Always level the deck side to side before making a
front to back adjustment.
Position the blade nearest the side discharge chute so
that the ends now point toward the front and back of the
mower.
Measure the distance from the tip of the blade to the
ground. For best results, the front tip of the blade should
be from 1/8 in. to 3/8 in. lower than the rear tip.

If front-to-back adjustment is needed, turn the adjustment
nuts clockwise to raise or counterclockwise to lower the
back of the cutting deck. Each full turn of the adjustment
nut will change the deck height approximately 1/8 in.
NOTE: Make sure to turn the adjustment nuts on both
sides equally to prevent throwing the side-to-side mea-
surement off again.
Measure again to verify the front tip is now 1/8 in. to
3/8 in. lower than the rear tip. If not, continue to adjust
and measure until they are.
Without moving the adjustment nuts, retighten the jam
nuts to secure the adjustment nuts in place.
