SERVICE AND ADJUSTMENTS FRONT-TO-BACK ADJUSTMENT (See Figs. 25 and 26) To obtain the best cutting results, the mower housing should be adjusted so the back is approximately 7/8" to 1-1/8" higher than the front when the mower is in height adjustment position. Measure distance "D" from ground line to bottom of deck curl at centerline outside of mandrels. • To raise rear of mower, loosen nut "E" on both rear suspension arms. Screw both nuts "F" on both rear suspension arms an equal number of turns. • When distance "D" is 7/8" to 1-1/8" higher at rear than front, retighten nuts "E". • Recheck side-to-side adjustment. IMPORTANT: WHEN ADJUSTING REAR SUSPENSION ARMS, ALWAYS ADJUST BOTH EQUALLY SO MOWER WILL STAY LEVEL SIDE-TO-SIDE. TO ADJUST ATTACHMENT CLUTCH (See Fig. 27) The electric clutch should provide years of service. The clutch has a built-in brake that stops the pulley within 5 seconds. Eventually, the internal brake will wear so the mower blades will not stop as recommended. Adjustments should be made by authorized service technician. • Make sure attachment clutch and ignition switches are in the "OFF" position. • Adjust the three nylon locknuts until the space between clutch plate and rotor measures .012 inches at all three slot locations cut in side of brake plate. NOTE: After installing a new electric clutch, run tractor at full throttle, and engage and disengage electric clutch 10 cycles to wear in clutch plate.
