Safety back toward the operator. Stop the blade(s) when crossing gravel surfaces. This machine meets or exceeds the B71.1-2003 specifications of the American National Standards Institute, in effect at the 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.
• Choose a low ground speed so you will not have to stop while operating on a slope. • Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and loss of control. • Always keep the drive wheels engaged when going down slopes. • Reduce speed and use extreme caution on slopes. • Do not make sudden turns or rapid speed changes. • Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

Motion Control Levers and Parking Brake Position Controls Become familiar with all of the controls in Figure 4 and Figure 5 before you start the engine and operate the machine. The motion control levers are speed sensitive controls of independent wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved.
Height-of-Cut Lever Operation The height of cut lever allows the operator to lower and raise the deck from the seated position. When the lever is moved up, toward the operator the deck is raised from the ground and when moved down, away from the operator it is lowered toward the ground. Only adjust the height of cut while machine is not moving (Figure 4). Note: Determine the left and right sides of the machine from the normal operating position.
DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
• The blades are disengaged. • The motion control levers are in the park position. Overfilling may result in fuel leakage or damage to the engine or emission system. The safety interlock system also is designed to stop the engine whenever the control levers are out of the park position and you rise from the seat. 1. Clean around the fuel tank cap and remove the cap. Before Starting 2. Slowly add regular, unleaded gasoline until the fuel reaches the base of the filler neck (Figure 10).
Starting the Engine 5 1. Sit down on the seat and move the motion controls outward to the park position. 2. Move the throttle control to fast (Figure 12). 3.

Cut 1/3 of the Grass Blade DANGER Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.
shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil. Before each use or daily • • • • • • Check the safety interlock system. Check the engine oil level. Clean the air intake screen. Check the cutting blades. Inspect the grass deflector for damage Clean the mower housing.
Premaintenance Procedures Lubrication Raising the Seat Service Interval: Every 25 hours—Grease all lubrication points. Greasing the Bearings Make sure the motion control levers are locked in the park position. Lift the seat forward. Grease Type: No. 2 General Purpose Lithium Base Grease The following components can be accessed by raising the seat: 1. Park the machine on a level surface and disengage the blade control switch. • Serial plate 2.
Engine Maintenance 4. Connect a grease gun to each fitting (Figure 25 and Figure 26). Pump grease into the fittings until grease begins to ooze out of the bearings. Servicing the Air Cleaner 5. Wipe up any excess grease. Note: Service the air cleaner more frequently (every few hours) if operating conditions are extremely dusty or sandy. Removing the Element 1. Park the machine on a level surface and disengage the blade control (PTO). 2.
1. Lightly tap the element on a flat surface to remove dust and dirt. 2. Inspect the element for tears, an oily film, and damage to the seal. 2. Make sure the engine is stopped, level, and is cool so the oil has had time to drain into the sump. 3. To keep dirt, grass clippings, etc., out of the engine, clean the area around the oil fill cap/dipstick before removing it. 4. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position (Figure 29).
2. Disengage the PTO, move the motion control levers to the neutral locked position and set the parking brake. 4. Slowly pour approximately 80% of the specified oil into the filler tube and slowly add the additional oil to bring it to the Full mark (Figure 31). 3. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position (Figure 30).
Removing the Spark Plug 2. Change the engine oil filter (Figure 32). 1. Disengage the PTO, move the motion control levers to the neutral locked position and set the parking brake. 2 1 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3 5 4 Figure 33 6 Note: Due to the deep recess around the spark plug, blowing out the cavity with compressed air is usually the most effective method for cleaning.
Installing the Spark Plug Fuel System Maintenance Tighten the spark plug(s) to 16 ft-lb (22 N-m). DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Perform any fuel related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills.
Electrical System Maintenance 4. Squeeze the ends of the hose clamps together and slide them away from the filter (Figure 36). 5. Remove the filter from the fuel lines. 6. Install a new filter with the flow direction arrow coming from the fuel tank and pointing to the engine. Move the hose clamps close to the filter (Figure 36) to secure it in place.
WARNING Incorrect battery cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. • Always connect the positive (red) battery cable before connecting the negative (black) cable. Figure 38 5. Slide the rubber cover up the positive (red) cable. Disconnect the positive (red) cable from the battery post (Figure 37).
Drive System Maintenance 30 Checking the Tire Pressure 25 Service Interval: Every 25 hours—Check tire pressure. 30 Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut. Check the pressure at the valve stem (Figure 40). Check the tires when they are cold to get the most accurate pressure reading. 1 25 2 G014921 Figure 39 1. Main-30 amp Refer to the maximum pressure suggested by the tire manufacturer on the sidewall of the caster wheel tires.
1. Locate the shaft on the electric brake where the brake link arms are connected. Mower Maintenance 2. Rotate the shaft forward to release the brake. Servicing the Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage.
