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 ap-
pearance of your lawn and lead you to think the mower is
not adjusted properly.

1. With all tires properly inflated and ifyour lawn appears un-
evenly 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 (Fig. 1).
NOTE: Each full turn of adjustment nut will change mower
height about 3/16".
4. Test your adjustment by mowing some uncut grass and
visually checking the appearance. Readjust, if necessary,
until you are satisfied with the results.

and/or wrap blade with heavy cloth.
2. Raise mower to its highest position.
3. At both sides of mower, position blade at side and mea-
sure the distance (A) from bottom edge of blade to the
ground. The distance should be the same on both sides

sides are equal.
FRONT-TO-BACK ADJUSTMENT

of the blade (Fig. 3).
If front tip of blade is not 1/8" to 1/2" lower than the rear
tip, go to the front of tractor.
With an 11/16" or adjustable wrench, loosen jam nut A
several turns to clear adjustment nut B.
With a 3/4" or adjustable wrench, turn front link adjustment
nut (B) clockwise (Itighten) to raise the front of mower, or,
counterclockwise (loosen) to lower the front mower (Fig. 4).
