[. . . ] SAFETY REQUIRES GOOD JUDGEMENT, CAREFUL USE IN ACCORDANCE WITH INSTRUCTIONS AND COMMON SENSE. MANUAL NO. 539104771 REV. 01 (05/23/00) Congratulations on the purchase of your Husqvarna mower. This manual has been prepared for the owners and operators of the Zero Turn Large Frame 52" and 61" commercial mowers. Read, understand and follow the safety and operating instructions. ! [. . . ] NOTE: make sure deck lift blocks are tightly bolted to the frame (See Fig 3). Return the deck height lever to the transport position (5" cutting height) and check the center to center distance of the swivels. Check the distance between the washers on the deck lift springs. Distance should be 11-3/4" (See Fig 3). If unequal, adjust upper chain bolt in slot. Place deck in the 5" cutting height and measure from the cutting edge of the blade to a flat surface to check deck cutting height. 7 ADJUSTMENTS Figure 3 MULE DRIVE BELT TENSION: 1. Check to make sure the bolt head in the spring loaded idler pulley, on the left side of the engine deck is positioned between the two alignment holes in the left support plate (See Fig 4). If adjustment is necessary, loosen the adjustable idler pulley on the right hand side of the engine deck so it can move up and down in the slot. Place a wrench on the 3/8" nut in the center of the spring loaded idler pulley and rotate the idler upward to relieve the tension on the belt. Reposition the right side pulley in the slot and tighten. Loosen the nuts directly behind each ball joint on both rods that connect the pump arm to the motion control assemblies. The park brake must be engaged and the motion control levers must be in the neutral slot (See figure 6 page10) to start the engine. Run engine at approximately 1/ 2 throttle. Release park brake to allow wheels to rotate. CAUTION: Keep hands, feet and clothing away from rotating tires. Begin with either side and put the motion control lever into the neutral position. Adjust the motion control linkage by rotating the double nuts on the rod in the proper direction until the wheel stops rotating (See Fig 5 ). Move the motion control lever forward then into the neutral position and place it into the neutral slot. The wheel must be stopped completely at this point. Now do the same in reverse and release the lever. The lever should return to neutral on its own. [. . . ] Front caster pivots Front wheels Deck lift blocks Park brake assemblies 12.
