TO LEVEL MOWER
Make sure tires are properly inflated to
the PSI shown on tires. If tires are over
or under inflated, it may affect the appear-
ance of your lawn and lead you to think
the mower is not adjusted properly.
VISUAL SIDE-TO-SIDE ADJUSTMENT
1. With all tires properly inflated and if
your lawn appears unevenly cut, de-
termine which side of mower is cutting
lower.
2. With a 3/4" or adjustable wrench, turn
lift link adjustment nut (A) to the left to
lower LH side of mower, or, to the right
to raise LH side of mower.
NOTE: Each full turn of adjustment nut will
change mower height about 3/16".
FRONT-TO-BACK ADJUSTMENT
IMPORTANT: Deck must be level side-
to-side.
To obtain the best cutting results, the
mower blades should be adjusted so the
front tip is 1/8" to 1/2" lower than the rear
tip when the mower is in its highest posi-
tion.
Ai_ CAUTION: Blades are sharp. Protect
your hands with gloves and/or wrap blade
with heavy cloth.
• Raise mower to highest position.
• Position any blade so the tip is pointing
straight forward. Measure distance (B)
to the ground at front and rear tip of the
blade.

uncut grass and visually checking the
appearance. Readjust, if necessary,
until you are satisfied with the results.
