Controls reverse; wheel speed is proportional to the amount the lever is moved. Moving the control levers outward from the center position engages the parking brake and allows the operator to exit the machine (Figure 13). Always position the motion control levers into the park position when you stop the machine or leave it unattended. Become familiar with all of the controls in Figure 3, Figure 4, and Figure 5 before you start the engine and operate the machine.
Operation Recommended Fuel Note: Determine the left and right sides of the machine from the normal operating position. Use Unleaded Regular Gasoline suitable for automotive use (87 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Think Safety First 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.
Add the correct amount of gas stabilizer/conditioner to the gas. 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. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Locate the bypass levers at the rear of the machine, on the left and right side of the frame. 4.
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. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. Figure 18 1. Knob 3. Baffle stud coming through the mower 2.
Cutting a Lawn for the First Time Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut. Open holes in the mower expose you and others to thrown debris which can cause severe injury.
lawn. To avoid this, move onto a previously cut area with the blades engaged. Keep the Underside of the Mower Clean Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory. Blade Maintenance Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades.
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 Before each use or daily • • • • • • Check the safety interlock system. Check the air cleaner for dirty, loose or damaged parts. Check the engine oil level. Check air intake and cooling areas (clean as necessary). Check the cutting blades. 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 and lower it to the floor board. 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 21 and Figure 22). Pump grease into the fittings until grease begins to ooze out of the bearings. Servicing the Air Cleaner 5. Wipe up any excess grease. Service Interval: Before each use or daily—Check the air cleaner for dirty, loose or damaged parts. This engine is equipped with a replaceable, high density paper air cleaner element. Check the air cleaner daily or before starting the engine.
Replace a dirty, bent, or damaged element. Handle new elements carefully; do not use if the rubber seal is damaged. 1 4. Clean all air cleaner components of any accumulated dirt or foreign material. Prevent any dirt from entering the carburetor. 5. Install the air cleaner element with the pleated side “out” and seat the rubber seal onto the edges of the air cleaner base (Figure 23). 2 6. Reinstall the air cleaner cover and secure with the two knobs (Figure 23).
pouring when the oil reaches the bottom of the threads. Allow a minute or two for the oil to be absorbed by the filter material. 1. Start the engine and let it run until warm. 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. 3. Disengage the blade control switch and move the motion controls outward to the park position. 4.
Installing the Spark Plug 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. The spark plug is most accessible when the blower housing is removed for cleaning. Service Interval: Every 500 hours—Replace the spark plug. 1. Install the spark plug. Make sure that the air gap is set correctly. 3. Remove the spark plug and metal washer. 2. Tighten the spark plug to 30 ft-lb (41 N-m). 1 3.
Fuel System Maintenance 6 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. 1 3 5 • Perform any fuel related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. G005071 2 • Never smoke when draining gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes. 4 Figure 30 1. Fuel line from tank 2. Hose clamp 3.
Electrical System Maintenance 3 2 6 5 1 Charging the Battery 7 Removing the Battery 4 Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. G005072 • When removing or installing the battery, do not allow the battery terminals to touch any metal parts of the machine. Figure 31 1. 2. 3. 4.
Installing the Battery Drive System Maintenance 1. Position the battery in the tray with the terminal posts toward the operating position (Figure 31). 2. Install the positive (red) battery cable to the positive (+) battery terminal using the fasteners removed previously. Checking the Tire Pressure Service Interval: Every 25 hours—Check tire pressure. 3. Install the negative battery cable to the negative (-) battery terminal using the fasteners removed previously.
Mower Maintenance 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. Figure 35 1. Cutting edge 2. Curved area Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
Removing the Blades The blades must be replaced if a solid object is hit, if the blade is out of balance, or the blade is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards. Figure 39 1. Blade 2. Balancer Installing the Blades Hold the blade end using a rag or thickly-padded glove.
