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 appear-
ance 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.
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" lower than the rear
tip when the mower is in its highest posi-
_/bnCAUTION: 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 the blade.
