SERVICE AND ADJUSTMENTS
FRONT-TO-BACK ADJUSTMENT (See Figs. 28 & 29)
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 blade so the tip is pointing straight forward.
Measure distance (B) to the ground at front and rear
tip of the 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.
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. 26)
• With all tires properly inflated and if your lawn appears
unevenly cut, determine which side of mower is cutting
lower.
• 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.
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.
PRECISION SIDE-TO-SIDE ADJUSTMENT (See Fig. 27)
• With all tires properly inflated, park tractor on level
ground or driveway.
CAUTION: Blades are sharp. Protect
your hands with gloves and/or wrap
blade with heavy cloth.
• Raise mower to its highest position.
• At both sides of mower, position blade at side and
measure the distance (A) from bottom edge of blade to
the ground. The distance should be the same on both
sides.
• If adjustment is necessary, see steps in Visual Adjust-
ment instructions above.
• Recheck measurements, adjust if necessary until both
sides are equal.
NOTE: Each full turn of the adjustment nut will change
mower height about 1/8" (3,1 mm).
• Recheck measurements, adjust if necessary until front
tip of blade is 1/8" to 1/2" (3,1 to 12,7 mm) lower than
the rear tip.
• Hold adjustment nut in position with wrench and tighten
jam nut securely against adjustment nut.
