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, determine
which side of mower is cutting lower.
NOTE: As desired, you can raise the low
side of mower or lower the high side.
2. Go to side of mower you wish to adjust.
3. With a 3/4" or adjustable wrench, turn
lift link adjustment nut (A) to the left
to lower the mower, or, to the right to
raise the mower.
