FOREWORD The Guardian® 72” Recycler® Cutting Deck has advanced concepts in engineering, design and safety; and if maintained properly, will give excellent service. Since this is a high-quality product, Toro is concerned about the future use of the machine and the safety of the user. Therefore, read this manual to familiarize yourself with proper operation and maintenance instructions. The major sections of the manual are: Certain information in this manual is emphasized.
Safety Training 1. Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. 2. Never allow children or people unfamiliar with these instructions to use the lawnmower. Local regulations may restrict the age of the operator. 3. 3. WARNING—Petrol is highly flammable. • Store fuel in containers specifically designed for this purpose. • Refuel outdoors only and do not smoke while refueling. • Add fuel before starting the engine.
Travel on grass slopes requires particular care. To guard against overturning: • do not stop or start suddenly when going up or downhill; 13.
7. If the fuel tank has to be drained, this should be done outdoors 8. On multi-bladed machines, take care as rotating one blade can cause other blades to rotate. 9. When machine is to be parked, stored or left unattended, lower the cutting means unless a positive mechanical lock is used. Sound & Vibration Levels Sound Levels This unit has an equivalent continuous A-weighted sound pressure at the operator ear of: 90 dB(A), based on measurements of identical machines per 84/538/EEC.

Specifications Width of Cut: 72 inches (183 cm) Height of Cut: Adjustable from 5–12.7 cm in 1.25 cm increments. Cutter Housing: 12-gauge steel and reinforced with 2-1/2" x 10 gauge channel. Cutting Unit Drive: Power is transmitted to the blades by one hex B section belt. Spindle shafts are 3.2 cm diameter and supported by two externally-sealed, greaseable, tapered roller bearings. Cutting Unit: The cutting unit has front and rear castor wheels, and three heat-treated steel blades 63.5 cm long and 6.
case and add enough lubricant to bring it up to the bottom of the hole in side. ADJUSTING HEIGHT-OF-CUT (Fig. 2–3) The height-of-cut is adjustable from 5 to 12.7 inches in 1.3 cm increments, by adding or removing an equal number of spacers from the front and rear castor forks. The height-of-cut chart below gives the combinations of spacers to use for all height-of-cut settings. Height of Cut Setting 5 cm 6.3 cm 7.6 cm 8.9 cm 10.1 cm 11.4 cm 12.7 cm 1.
Operating Instructions 3. Install the lynch pin to secure the assembly . 4. Assure all four castor wheels are set at same height-of-cut. ADJUSTING SKIDS (Fig. 4) 1. Adjust skids by loosening flange nuts, positioning as desired and re-tightening the flange nuts. Figure 4 1. Skid OPERATING TIPS 1.
edges, which impairs growth and increases susceptibility to diseases. CAUTION: This product may exceed noise levels of 85 dB(A) at the operator position. Ear protectors are recommended for prolonged exposure to reduce the potential of permanent hearing damage. 6. STOPPING—If you stop while cutting, a clump of grass clippings may be deposited on lawn. Follow this procedure for stopping while cutting: A. With the deck engaged, move onto a previously cut area. B. 7.
bottom of the hole. If the level is low, remove the fill plug on top of the gear case and add SAE 80-90 weight gear lubrication until the level is up to the bottom of the hole in side. Figure 6 Figure 7 Figure 8 1. 2. 3.

CAUTION To prevent accidental starting of the engine while performing maintenance, shut of the engine and remove the key from the ignition switch. SEPARATING THE CUTTING UNIT FROM THE TRACTION UNIT (Fig 9–11) 1. Position the machine on level surface, lower the cutting unit to the floor, shut the engine off and engage the parking brake. Figure 9 2. Remove the self-tapping screws securing the shield to the top of the cutting unit and set the shield aside. 3.
remove the capscrews, flatwashers and locknuts securing the ball joint mount to the castor arm on the cutting unit. Now the helper can carefully allow the push arm to move upward, which will gradually release the spring load. 7. Roll the cutting unit away from the traction unit. MOUNTING THE CUTTING UNIT TO THE TRACTION UNIT (Fig 9–11) 1. Position the machine on a level surface and shut the engine off. 2. Move the cutting unit into position in front of the traction unit. Figure 12 1. 2. 3.
8. Line up the holes in the yoke and the input shaft of the gear box. Slide the yoke onto the shaft and secure together with a roll pin and two 5⁄16-18 x 1-3⁄4 inch long capscrews and 5⁄16-18 locknuts. REPLACING THE DRIVE BELT (Fig 12–14) The blade drive belt, tensioned by the spring-loaded idler pulley, is very durable. However, after many hours of use, the belt will show signs of wear.
the tube and after many hours of operation, the bushings will wear. To check the bushings, move the castor fork back and forth and from side to side. If the castor spindle is loose inside the bushings, bushings are worn and must be replaced. 1. Raise the cutting unit so its wheels are off the floor and block it so that it cannot fall accidentally. 2. Remove the lynch pin, spacer(s) and thrust washer from top of the castor spindle. 3. Pull the castor spindle out of the mounting tube.
4. Check the bearing, spanner and inside of the wheel hub for wear. Replace defective parts. 5. To assemble the castor wheel, push the bushing into wheel hub. Slide the bearing into the wheel hub. Push the other bushing into the open end of the wheel hub to captivate the bearing inside the wheel hub. 6. Carefully slide the spanner through the bushings and the wheel hub. 7. Install the castor wheel assembly between the castor fork and secure in place with a capscrew and locknut. Figure 17 8.
3. Install blade–sail facing toward the cutting unit with the cup, lockwasher and blade bolt. Tighten the blade bolt to 85-110 ftlb. INSPECTING AND SHARPENING BLADE (Fig. 18–19) 1. Raise the cutting unit to the highest position, shut the engine off and engage the parking brake. Block the cutting unit to prevent it from falling accidentally. 2. Examine the cutting ends of the blade carefully, especially where the flat and curved parts of the blade meet (Fig. 26-A).
CORRECTING CUTTING UNIT MISMATCH If there is mismatch between the blades, the grass will appear streaked when it is cut. Correct this by making sure the blades are straight and all blades cut on the same plane. 1. Using a 1-meter long carpenters level, find a level surface on the shop floor. 2. Raise the height of cut to the highest position. 3. Lower the cutting unit onto a flat surface. Remove the covers from the top of the cutting unit. 4. 5.
