TO LEVEL MOWER
Make sure tires are properly infl ated to the PSI shown on
tires. If tires are over or under infl ated, it may affect the
appearance of your lawn and lead you to think the mower
is not adjusted properly.

• With all tires properly infl ated and if your lawn appears
unevenly cut, determine which side of mower is cutting
lower.
NOTE: As desired, you can raise the low side of mower or
lower the high side.
• Go to side of mower you wish to adjust.
• With a 3/4" or adjustable wrench, turn lift link adjust-
ment nut (A) to the left to lower the mower, or, to the
right to raise the mower.
NOTE: Each full turn of adjustment nut will change mower
height about 3/16".
• Test your adjustment by mowing some uncut grass and
visually checking the appearance. Readjust, if neces-
sary, until you are satisfi ed with the results.
