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 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.
NOTE: Each full turn of adjustment nut will
change mower height about 3/16".
