SERVICE AND ADJUSTMENTS
FRONT-TO-BACK ADJUSTMENT (See Figs. 38 & 39)
IMPORTANT:
Deck must be level side-to-side.
To obtain the best cutting re sults, 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 the blade.
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 appear-
ance of your lawn and lead you to think the mower is not
adjusted properly.
VISUAL SIDE-TO-SIDE ADJUSTMENT (See Fig. 36)
• 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.
• Go to side of mower you wish to adjust.
• 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.
NOTE
: Each full turn of adjustment nut will change mower
height about 3/16" (4,7 mm).
• Test your adjustment by mowing some uncut grass and
visually checking the appearance. Readjust, if neces-
sary, until you are satisfied with the results.
