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.

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

sary until both sides are equal.

position.

your hands with gloves and/or wrap blade

straight forward. Measure distance "B" to
the ground at front and rear tip of blade.
If front tip of blade is not 1/8 to 1/2" (3,1
to 12,7 mm) lower than the rear tip, go to
the front of tractor.
