SERVICE AND ADJUSTMENTS

TO LEVEL MOWER HOUSING (See Fig. 23 -

Fig. 26)

Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly inflated (See "PRODUCT SPECIFICATIONS" on page 3). If tires are

over or under inflated, you will not properly adjust your mower.

NOTE: One rotation of trunnion nut is equivalent to ap- proximately 1/8 inch of height change. Be sure upper and lower nuts are tightened against trunnion after adjustment has been completed.

•Place mower height adjustment knob in position "3" (See Fig. 23).

•Lower mower lift lever to height adjustment knob.

SIDE-TO-SIDE ADJUSTMENT (See Figs. 24 and 25) -

•Measure distance from ground to lower flange of mower deck on both sides of mower (dim. "B°'& "C"). Dim. "B"

&"C" should be the same.

Level the mower side-to side by adjusting the left rear lift link.

•To raise left side of mower, loosen upper trunnion nut tighten the lower trunnion nut.

•To lower left side of mower, loosen lower trunnion nut and tighten upper trunnion nut.

FRONT-TO-BACK ADJUSTMENT (See Figs. 25 and 26)-

To obtain the best cutting results, the mower housing should be adjusted so the rear is approximately 1/4 to 3/8" higher than the front when the mower is in height adjust- ment position "3".

•Measure distance from ground line to lower flange of deck at right front and right rear (dim. "D" & "E") in line with front and rear tires.
