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.
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.
5. Recheck measurements; adjust if neces-
sary until both sides are equal.
FRONT-TO-BACK ADJUSTMENT
IMPORTANT: Deck must be level side-
to-side.
To obtain the best cutting results, the mower
blades should be adjusted so the front tip
is 1/8 to 1/2" (3,1 to 12,7 mm) (lower than
the rear tip when the mower is in its highest
position.
,_CAUTION: Blades are sharp. Protect
your hands with gloves and/or wrap blade
with heavy cloth.
• Raise mower to highest position.
• Position any blade so the tip is pointing
straight forward. Measure distance "B" to
the ground at front and rear tip of blade.
