SERVICE AND ADJUSTMENTS

adjusted properly.

unevenly cut, determine which side of mower is cutting
lower.
• 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.

sary, until you are satisfied with the results.
