BEFORE OPERATING ADJUSTING HEIGHT OF CUT REAR CASTOR WHEELS The height of cut is adjustable from 1 to 4 inches in 1/4 inch increments. 1. Start the engine and raise the cutting unit so height of cut can be changed. Stop engine after cutting unit is raised. Figure 20 FRONT CASTOR WHEELS 1. Remove hairpin cotter and cotter pin securing rear castor pivot arm to deck bracket. Figure 18 1 1. Remove H.O.C. cap from spindle shaft and slide spindle out of front castor arm.
BEFORE OPERATING ADJUST ROLLERS The front anti scalp rollers and the rear anti scalp rollers, located on the center deck, should be located in upper holes for 1 and 1 1/2 inch heights of cut and lower holes for 2 to 5 inch heights of cut. Six rollers are located on the deck, two under the main deck and two on each wing. Figure 23 CHECK TIRE PRESSURE Ensure that the air pressure in the front and rear castor wheels is 40 psi (276 kPa).
OPERATING INSTRUCTIONS GRASS DEFLECTOR (Fig. 26) WARNING OPERATING TIPS 1. MOW WHEN GRASS IS DRY-Mow either in the late morning to avoid the dew, which causes grass clumping or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass. The grass deflector (Fig. 26) is a safety device that diverts grass and other foreign objects being discharged downward.
LUBRICATION GREASING THE CUTTING UNIT The cutting unit must be lubricated regularly. If machine is operated under normal conditions, lubricate castor bearings and bushings with No. 2 general purpose lithium base grease or molybdenum base grease, after every 8 hours of operation or daily, whichever comes first. 1. The cutting unit has bearings and bushings that must be lubricated, and these lubrication points are: front castor spindle bushings (2) (Fig. 27); front castor wheel bearings (4) (Fig.

MAINTENANCE CAUTION To prevent accidental starting of the engine, while performing maintenance, shut engine off and remove key from ignition switch. SEPARATING CUTTING UNIT FROM TRACTION UNIT 1. Position machine on level surface, lower cutting unit to floor, shut engine off and engage parking brake. 2. Remove self tapping screws securing shield to top of cutting unit and set shield aside. 3. Drive out roll pin securing drive shaft yoke to input shaft of gear box.
MAINTENANCE SERVICING FRONT BUSHINGS IN CASTOR ARMS The castor arms have bushings pressed into the top and bottom of the tube and after many hours of operation, the bushings will wear. To check the bushings, move castor fork back and forth and from side to side. If castor spindle is loose inside the bushings, bushings are worn and must be replaced. 1 Figure 33 1. Spring tensioning rod (3) REPLACING DRIVE BELTS The blade drive belts, tensioned by the spring loaded idlers, are very durable.
MAINTENANCE 1. Remove locknut from capscrew holding castor wheel assembly between castor fork. Grasp castor wheel and slide capscrew out of fork. 2. Pull spanner bushing out of wheel hub. 2. Remove two capscrews, locknuts, and springs securing deflector mounts to pivot brackets. 3. To remove the pivot brackets, remove carriage bolts and nuts. 4. Reinstall pivot brackets on top of discharge opening with carriage bolts and nuts. Head of carriage bolts must be on inside of cutting unit. 5.
MAINTENANCE 3 2 1 Figure 38 1. Blade bolt 2. Lockwasher 3. Anti-Scalp Cup Figure 39 DANGER 2. Install blade sail facing toward cutting unit with anti scalp cup, lock washer, and blade bolt. Tighten blade bolt to 85-110 ft. lb. WARNING Do not try to straighten a blade that is bent, and never weld a broken or cracked blade. Always use a new blade to ensure continued safety certification of the product. INSPECTING AND SHARPENING BLADE 1.
MAINTENANCE CORRECTING CUTTING UNIT MISMATCH If there is mismatch between the blades, the grass will appear streaked when it is cut. This problem can be corrected by making sure the blades are straight and all blades are cutting on the same plane. 1. Using a 3 foot long carpenters level, find a level surface on the shop floor. 2. Raise height of cut to the highest position: refer to Adjusting Height of Cut. 3. Lower cutting unit onto flat surface. Remove covers from top of cutting unit. 4.
