SAFETY INSTRUCTIONS The GROUNDSMASTER 455-D was tested and certified by TORO for compliance with the B71.4-1999 specifications of the American National Standards Institute. Although hazard control and accident prevention partially are dependent upon the design and configuration of the machine, these factors are also dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine.
SAFETY INSTRUCTIONS 15. Traverse slopes carefully. Do not start or stop suddenly when traveling uphill or downhill. Never shift axle when moving. Machine must be on a flat surface and / or brakes must be engaged to prevent freewheeling. 16. Operator must be skilled and trained in how to drive on hillsides. Failure to use caution on slopes or hills may cause loss of control and vehicle to tip or roll possibly resulting in personal injury or death. 17.
SAFETY AND INSTRUCTION DECALS The following safety and instruction decals are affixed to the cutting unit. If any decal becomes illegible or damaged, install a new decal. Part numbers are listed below and in your Parts Catalog. UNDER DECK COVERS (3) (Part No. 85–6410) Replace Cover Before Operating ON LEFT CASTOR ARM (Part No. 86–0720) Height–of–cut Adjusting Procedure ON CUTTING DECKS (5) (Part No. 55–4300) Spring Loaded ON RIGHT CASTOR ARM (Part No.

SET–UP INSTRUCTIONS MOUNTING CUTTING UNIT TO TRACTION UNIT (Fig. 1–3) Note: Before installing cutting unit on a used traction unit, inspect lift arm ball joints to make sure they are not worn or damaged. Replace, if necessary. 1. With cutting unit on a level surface, move traction unit into position, aligning drive shaft yoke with gear box input shaft and lift arm ball joints with mounting holes in castor arms. Shut engine off. 2.
BEFORE OPERATING CHECK LUBRICANT IN GEAR BOX 2 (Fig. 4) The gear box is designed to operate on SAE 80–90 wt. gear lube. Although the gear box is shipped with lubricant from the factory, initially, check the level before operating the cutting unit and every 50 hours thereafter. Check daily for signs of oil loss. 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.
BEFORE OPERATING SAFETY DOORS (Fig. 8) On each side of the center deck is a safety door that opens and closes as the wing decks are lowered and raised (Fig. 8). The doors open to provide overlap of the cutting blades when the wing units are down. The doors close to provide safety and protection when the wing units are raised. Check to make sure the forward, lower edge of door is even or 1/4” higher then lower edge of door guide when wing decks are in the fully raised, transport position.
OPERATING INSTRUCTIONS Transport – When mowing is complete, disengage cutting unit and raise it by pulling back on cutting unit lift control levers. Hold levers back until cutting unit is fully raised. Never raise cutting deck when engaged. Lock cutting unit in place with transport latches. Move axle shift lever forward to HI position. When driving from one area to another, always shift axle to LO position before encountering a slope. Never shift from HI to LO position while on a slope.
OPERATING INSTRUCTIONS Select The Proper Height–of–cut Setting To Suit Conditions – Remove approximately one inch or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass you may have to raise your height–of–cut setting another notch. Mowing In Extreme Conditions – Air is required to cut and recut grass clippings in mower housing, so do not set height–of–cut too low or totally surround housing by uncut grass.
LUBRICATION GREASING (Fig. 9–13) The cutting unit has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. If machine is operated under normal conditions, lubricate all grease fittings after every 25 hours of operation. Lubricate all grease fittings immediately after every washing, regardless of interval listed. The grease fittings that must be lubricated are: blade spindles (7), lift cylinder ball joints (4) and Wing Deck Pivot pins (4) (Fig.
MAINTENANCE CAUTION 2 To prevent accidental starting of the engine, while performing maintenance, shut engine off and remove key from ignition switch. 1 GENERAL MAINTENANCE Note: Although not required for normal maintenance procedures, the cutting unit may be pivoted (tilted) to a upright position. Should you desire to tilt the cutting unit, use the following procedure: To Pivot (Tilt) Cutting Unit Upright: 1. Drive machine onto ramps to raise front of machine. 2.
MAINTENANCE 3. Line up holes in yoke and input shaft of gear box. Slide yoke onto shaft and secure together with socket head screws. Torque screws to 20–25 ft–lb. 4. Start engine, raise center cutting unit slightly, so rear deck straps can be mounted on lift arm brackets. Stop engine after cutting unit is raised. 5. Secure rear deck straps to H.O.C. brackets on deck with hair pin cotters and H.O.C. pins. Start engine and lower center cutting unit completely to floor.
MAINTENANCE ADJUSTING BELT TENSION (Fig. 21) CAUTION Each cutting unit drive belt is individually tensioned by a self tensioning spring loaded idler. When the idlers are properly adjusted, the black plastic sleeve should be .12” to .25” from the edge of the idler support. When .50” of the plastic sleeve is exposed, an adjustment is required.
MAINTENANCE To Remove Wing Deck Belts To Remove Center Deck Belt WARNING WARNING Idler pulley spring loaded, use caution when relieving spring tension on wing belt. Idler pulley spring loaded, use caution when relieving spring tension on center belt. 2. To relieve tension on wing belt, pull back on idler pulley until holes in idler adjustor tube and tube sleeve are aligned. Thread a 5/16–18 capscrew into holes retaining parts. 5.
MAINTENANCE 13. Remount clutch rod to deck with hair pin cotter and plug clutch connector into harness. 14. While holding idler pulley adjustor in position, carefully remove capscrew securing idler adjustor tube to tube sleeve. Allow idler pulley to release, tensioning belt. 15. Check idler pulley adjustment, refer to Adjusting Belt Tension, page 37. 16. Reinstall belt covers. 2. Remove HOC cap and spacer(s) from top of castor spindle. 3. Pull castor spindle out of mounting tube.
MAINTENANCE 2. Remove bearing from wheel hub and allow bearing spacer to fall out. Remove bearing from opposite side of wheel hub. 3. Check the bearings, spacer and inside of wheel hub for wear. Replace defective parts. 4. To assemble the castor wheel, push bearing into wheel hub. Slide bearing spacer into wheel hub. Push other bearing into open end of wheel hub to captivate the bearing spacer inside the wheel hub. 5.
2. Inspect cutting edges of all blades. Sharpen the cutting edges if they are dull or nicked. Sharpen only the top of the cutting edge and maintain the original cutting angle to make sure of sharpness (Fig. 32). The blade will remain balanced if same amount of metal is removed from both cutting edges. 4. To check blade for being straight and parallel, lay blade on a level surface and check its ends.
