TO LEVEL MOWER
Ensure tires are properly inflated to the PSI
shown on tires. If tires are over or under
inflated, it may affect the appearance 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.
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.

3. Test your adjustment by mowing some
uncut grass and visually checking the
appearance. Readjust, if necessary, until
you are satisfied with the results.
PRECISION SIDE-TO-SIDE ADJUSTMENT

your hands with gloves and/or wrap blade
with heavy cloth.

bottom edge of blade to ground. The dis-
tance should be the same on both sides.
