Introduction Safety Read this manual carefully to learn how to operate and maintain your product properly. The information in this manual can help you and others avoid injury and product damage. Although Toro designs and produces safe products, you are responsible for operating the product properly and safely. This tractor meets or exceeds the B71.1–1998 specifications of the American National Standards Institute in effect at the time of production.
• Watch for traffic when operating near or crossing roadways. Children • Use extra care when loading or unloading the machine into a trailer or truck. Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them. • Always wear safety goggles or safety glasses with side shields when operating mower.
• Do not use a grass catcher on steep slopes. Heavy grass bags could cause loss of control or overturn the machine. • Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them. • Use only genuine Toro replacement parts to ensure that original standards are maintained.

4. Shift the blade control (PTO) lever to Disengaged (Fig. 8). Important If the engine does not start after 30 seconds of continuous cranking, turn the ignition key to Off and let the starter motor cool; refer to Troubleshooting on page 38. 2 7. After the engine starts, slowly shift the throttle lever to Fast (Fig. 9). If the engine stalls or hesitates, shift the throttle lever back to Choke for a few seconds. Then shift the throttle lever to Fast. Repeat this as required. 1 Stopping the Engine 1.
4. Shift into reverse and complete your task. Danger 5. Disengage the blades (PTO) to activate the interlock. You could back over a child or bystander while the mower blades or other attachment is engaged and cause serious injury or death. 6. Remove the KeyChoice key and put it in a safe place out of reach of children. • Do not mow in reverse unless absolutely necessary. • Do not insert the KeyChoice key unless it is absolutely necessary. • Always look backward and down before backing up.
Driving the Tractor Forward or Backward Caution Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended. The throttle control regulates the engine speed as measured in RPM (revolutions per minute). To go forward or backward, depress the clutch/brake pedal. shift the ground speed lever lever to the desired forward speed or reverse. As you slowly release the pedal, the tractor will begin to move. Steer the tractor with the steering wheel.
• Grass grows at different rates at different times of the season. To maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. 2. Lift the grass deflector and slide the tabs on top of the discharge cover under the grass deflector retaining rod. Rotate the discharge cover down over the opening, and onto the lower lip of the mower (Fig. 13). 3.

Servicing the Brake Greasing and Lubricating the Tractor The brake is on the right side of the rear axle, inside the rear tire (Fig. 21). If the brake does not hold securely or stopping power is insufficient, an adjustment is required. Grease the tractor after every 25 operating hours or once a year, whichever occurs first. Grease more frequently when operating conditions are extremely dusty or sandy. Checking the Brake Grease Type: General-purpose grease 1. Park the tractor on a level surface. 2.
Removing the Battery Checking the Tire Pressure Maintain the air pressure in the front and rear tires at 20 psi (138 kPa). Check the pressure at the valve stem after every 25 operating hours or yearly, whichever occurs first (Fig. 23). Check the tires when they are cold to get the most accurate pressure reading. Warning Battery terminals or metal tools could short against metal tractor components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.
3. If the electrolyte is low, add the required amount of distilled water; refer to Adding Water to the Battery on page 25. Warning Incorrect battery cable routing could damage the tractor and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. Danger Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns. • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.
Charging the Battery Draining the Fuel Tank Warning Danger Charging the battery produces gasses that can explode. 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. Never smoke near the battery and keep sparks and flames away from battery. • Drain gasoline from the fuel tank when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills.
Replacing the Fuel Filter Servicing the Headlights Replace the fuel filter after every 100 operating hours or yearly, whichever occurs first. Use a #1156, automotive-type bulb. The best time to replace the fuel filter (Fig. 27) is when the fuel tank is empty. Never install a dirty filter if it is removed from the fuel line. Removing the Bulb 1. Disengage the blades (PTO). 2. Shift the ground speed lever into Neutral. 2. Shift the ground speed lever into Neutral. 3. Set the parking brake. 3.
