SERVICE AND ADJUSTMENTS

• If adjustment is necessary, see step in Visual Adjust-

ment instructions above.

Recheck measurements, adjust if necessary until both

sides are equal.

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" 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.

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

appearance 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 adjust-

ment 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".
• Test your adjustment by mowing some uncut grass

and visually checking the appearance. Readjust, if

necessary, 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.

NOTE: Each full turn of the adjustment nut will change

mower height about 1/8".

Recheck measurements, adjust if necessary until front

tip of blade is 1/8" to 1/2" lower than the rear tip.
