BEFORE OPERATING CHECK LUBRICANT IN GEAR BOX The gear box in designed to operate on SAE 80-90 wt. gear lube. Although the gear box is shipped with lubricant from the factory, check the level before operating the cutting unit. 1. Position the machine and cutting unit on a level surface. 2. Remove check plug from side of gear box and make sure lubricant is up to bottom of hole. If level of lubricant is low, remove fill plug on top of gear case and add enough lubricant to bring it up to bottom of hole in side.
BEFORE OPERATING REAR DECK CHAIN 1. Remove hair pin cotter and clevis pin securing height-of-cut chain to chamber bracket. 2. Mount height-of-cut chain to desired height-of-cut hole with clevis pin and hair pin cotter. ADJUST SKID Skid, on right side of cutting unit, should be located in upper holes for 1 and 1-1/2 inch heights-of-cut and lower holes for 2 to 4 inch heights-of-cut. 1. Adjust skid by removing flange nuts, positioning as desired and re-installing flange nuts.
OPERATING INSTRUCTIONS GRASS DEFLECTOR (Fig. 24) WARNING The grass deflector (Fig. 24) is a safety device that diverts grass and other foreign objects being discharged downward. WE STRONGLY RECOMMEND THAT THE DEFLECTOR BE IN ITS NORMAL OPERATING POSITION WHENEVER THE CUTTING UNIT IS ENGAGED. NEVER OPERATE CUTTING UNIT WITH THE DEFLECTOR REMOVED FROM THE CUTTING UNIT OR IT TIED/BLOCKED IN A RAISED POSITION.
LUBRICATION GREASE BEARINGS, BUSHINGS AND GEAR BOX (Fig. 25-30 ) 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.
LUBRICATION 1 3 Figure 29 2. Position the machine and cutting unit on a level surface and lower cutting unit. Remove check plug from side of gear box (Fig. 30) and make sure lubricant is up to bottom of hole.

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 31 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 36 1. Blade bolt 2. Lockwasher 3. Anti-Scalp Cup Figure 37 DANGER 2. Install blade sail facing toward cutting unit with anti-scalp cup, lockwasher 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.
