SERVICE AND ADJUSTMENTS

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.

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 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 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.

With a 3/4" or adjustable wrench, turn front link adjust- ment nut (B) clockwise (tighten) to raise the front of mower, or, counterclockwise (loosen) to lower the front mower.
