Safety This machine meets or exceeds safety requirements B71.4–1990 of the American National Standards Institute for commercial mowers, in effect at time of production. However, improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol which means CAUTION, WARNING or DANGER—“personal safety instruction.
Safety D. Do not smoke while refueling. 6. 7. Keep all guards, shields, safety devices, cover-deflector assembly, optional grass catcher, optional side discharge chute or optional discharge tunnel plug in place. Repair or replace damaged parts, including decals. Check all safety devices before each use. Engine, blade and self–propelled drive (self-propelled model) are designed to stop when control bails are released. Ensure control and brake function properly before each use of mower. 8.
Safety Maintenance And Storage 1. Perform only those maintenance instructions described in this manual. If major repairs are ever needed or if assistance is desired, contact your local Authorized TORO Service Dealer. 2. Before mower is cleaned, inspected, serviced, or adjusted, stop engine and disconnect wire from spark plug. Keep wire away from plug to prevent accidental starting. 3. To ensure the mower is in safe operating condition, frequently check and keep all nuts, bolts, and screws tight.
Gasoline and Oil Recommended Gasoline Stabilizer/Conditioner Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Add the correct amount of gas stabilizer/conditioner to the gas. Using a stabilizer/conditioner in the machine: IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Operation Think Safety First Please carefully read all the safety instructions and symbols in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. Controls Become familiar with all the controls (Fig. 10) before you start the engine and operate the machine. Recoil Starter – Pull recoil Starter handle to start engine. Fuel Shut–off Valve – (Under fuel tank) Close fuel shut–off valve when transporting or storing mower.
Operation Parking Brake Always set the parking brake when you stop the machine or leave it unattended. Setting the Parking Brake 1. Pull the upper control bar (Fig. 11) rearward and hold it in this position. 2. Lift the parking brake lock (Fig. 11) up and gradually release the upper control bar. The brake lock should stay in the set (locked) position. Releasing the Parking Brake 1. Pull rearward on the upper control bar (Fig. 11). Lower the parking brake lock to the released position. 2.
Operation Starting and Stopping the Engine 2 Starting 1. Make sure spark plug wire(s) are installed on spark plug(s) and fuel valve is open. 2. Move the shift lever to neutral, set the parking brake and turn ignition key to RUN. 3. Move the throttle control to CHOKE position before starting a cold engine. Note: 4. A warm or hot engine usually does not require any choking. To start a warm engine, move throttle control to FAST position.
Operation Operating Mower Blade Control (PTO) The Safety Interlock System The blade control switch (PTO) in conjunction with the blade control bail engages and disengages power to the electric clutch and mower blades. Engaging the Mower Blades (PTO) 1. Pull on the upper control bar to stop the machine (Fig. 13). 2. To engage blade, squeeze blade control bail against upper control bar 3. Press rocker switch forward “ON” and release. Hold blade control bail against control bar while operating. 4.
Operation Driving Forward or Backward The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the “FAST” position for best performance. Forward 1. To go forward, move the shift lever to a forward gear. 2. Release the parking brake: refer to Releasing the Parking Brake, page 18. 3. Slowly press on the upper control bar to move forward (Fig. 14). To go straight, apply equal pressure to both ends of the upper control bar (Fig. 14).

Maintenance Air Cleaner Cleaning the Foam and Paper Elements 1. Service Interval/Specification Foam Element Foam Element: Clean and re-oil after every 25 operating hours. A. Wash the foam element in liquid soap and warm water. When the element is clean, rinse it thoroughly. Paper Element: Replace after every 100 operating hours. B. Dry the element by squeezing it in a clean cloth. C. Put one or two ounces of oil on the element (Fig. 16). Squeeze the element to distribute the oil.
Maintenance 2. Paper Element Engine Oil A. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 17). Service Interval/Specification B. Change oil: Inspect the element for tears, an oily film, and damage to the rubber seal. IMPORTANT: Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene. Replace the paper element if it is damaged, defective, or cannot be cleaned thoroughly. • After the first 8 operating hours.
Maintenance Checking Oil Level Changing/Draining Oil 1. 1. Start the engine and let it run five minutes. This warms the oil so it drains better. 2. Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains completely. Then disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key. 3. Place a pan below the oil drain. Remove the oil drain plug (Fig. 19). 4.
Maintenance Spark Plug Checking the Spark Plug 1. Service Interval/Specification Look at the center of the spark plug(s) (Fig. 21). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. Check the spark plug(s) after every 200 operating hours. Make sure the air gap between the center and side electrodes is correct before installing the spark plug.
Maintenance Greasing and Lubrication 2. Lubricate the transmission couplers (Fig. 23). Service Interval/Specification Grease the wheel bearings every 8 operating hours and the transmission couplers every 250 operating hours. Grease more frequently when operating conditions are extremely dusty or sandy. Grease Type: General-purpose grease. How to Grease m–2067 Figure 23 1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine.
Maintenance Brake Before each use, check brakes for proper operation. Always set the parking brake when you stop the machine or leave it unattended. If the parking brake does not hold securely, an adjustment is required. Checking the Brake 1. 2. Park the machine on a level surface, disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key. Rear wheels must lock when you try to push the machine forward.
Maintenance Fuel Tank Draining The Fuel Tank 1 2 POTENTIAL HAZARD • In certain conditions gasoline is extremely flammable and highly explosive. m–1717 WHAT CAN HAPPEN • A fire or explosion from gasoline can burn you, others, and cause property damage. Figure 26 1. Fuel shut-off valve 2. Clamp HOW TO AVOID THE HAZARD • Drain gasoline from the fuel tank when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills.
Maintenance Fuel Filter Replacing the Drive Belt Service Interval/Specification 1. Remove top capscrew securing idler support and idler bracket to rear frame (Fig. 28). Replace the fuel filter after every 100 operating hours or yearly, whichever occurs first. 2. Loosen bottom two mounting screws enough to allow belt to pass between drive pulley and idler support (Fig. 28). 3. Raise wheel off ground enough to allow belt removal.
Maintenance Replacing the Traction Belt Adjusting the Electric Clutch 1. Raise the front of the machine and hold with jack stands. The clutch is adjustable to ensure proper engagement and proper braking. Check adjustment after every 100 hours of operation. 2. Disconnect in–line wire connector from wire harness to electric clutch. 3. Remove left front engine mounting bolt securing clutch retainer to frame (Fig. 29). Unhook retainer from clutch and remove retainer. 4.
