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 machine meets or exceeds the B71.4–1999 specifications of the American National Standards Institute in effect at the time of production.
• Slow down and use caution when making turns and crossing roads and sidewalks. Stop blades if not mowing. • Use extra care when handling gasoline and other fuels. They are flammable and vapors are explosive. • Use only an approved container. • Be aware of the mower discharge direction and do not point it at anyone. • Never remove gas cap or add fuel with engine running. Allow engine to cool before refueling. Do not smoke. • Do not operate the mower under the influence of alcohol or drugs.
• Avoid starting or stopping on a slope. If tires lose traction, disengage the blades. This product is designed for cutting and recycling grass or, when equipped with a grass bagger, for catching cut grass. Any use for purposes other than these could prove dangerous to user and bystanders. • Mow slopes side-to-side. DO NOT General Operation • Do not mow slopes greater than 15 degrees. • Allow only responsible adults who are familiar with the instructions to operate the machine.

Note: Determine the left and right sides of the machine from the normal operating position. 10 1 5 2 7 Think Safety First Carefully read all the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets, or bystanders avoid injury.
respectively. The sharpness of the turn depends on how much you squeeze the drive lever. To move the mower straight forward (or backward), smoothly release both drive levers simultaneously. 2. Place your thumbs on the upper part of the locks and move them rearward until they are in the Drive position (Fig. 15). Neutral/parking brake locks—Squeeze the drive levers back and move the locks rearward to activate the neutral lock.
Note: If the engine has been working hard or is hot, let it idle for a minute before stopping it to help cool it. • The throttle is out of the Stop position. 2. Turn the ignition key to the Off position. • The machine is shifted into the Neutral position. • The blade control (PTO) lever is disengaged. 3. Set the parking brakes. The safety interlock system is designed to stop the engine when: 4.
Transporting the Mower 3. Move the shift lever into a forward gear. 4. Release the parking brakes; refer to Releasing the Parking Brakes, page 19. Use a heavy-duty trailer or truck to transport the mower. Ensure that the trailer or truck has all the necessary lighting and markings as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury. 5. Slowly release the drive levers.
Adjusting the Wheel Drive Tension Adjusting the Height-of-Cut This machine has a 1 to 4-1/4 inch (26 to 108 mm) range for the height-of-cut. This can be achieved by adjusting blade spacers, rear axle height, and front caster spacers. Use the Height-of-Cut Chart on page 24 to select the combination required. You may need to increase the wheel drive belt tension under certain operating conditions, such as mowing over hilly terrain or while pulling a sulky. 1.
2. Stop the engine and wait for all moving parts to stop before leaving the operating position. 1 2 3.

Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important Refer to your engine operator’s manual for additional maintenance procedures.
Caution Someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades 2. Inspect the blades, especially the curved area (Fig. 20). If you notice any damage, wear, or a slot forming in this area (item 3 in Fig. 20), immediately install a new blade. To ensure a superior quality of cut, keep the blades sharp.
2 Warning 1 A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. m–1854 • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of the blade. Figure 24 1. Sharpen at original angle 2. Sail 2. Check the balance of the blade by putting it on a blade balancer (Fig. 25). If the blade stays in a horizontal position, the blade is balanced and can be used.
Removing the Foam and Paper Elements Cleaning the Paper Element 1. Disengage the PTO, turn the ignition key to off, and remove the key. 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. 2. Wait for all moving parts to stop before leaving the operating position and then chock or block tires. 1.
Checking the Engine Oil Level 1. Park the machine on a level surface. 2. Disengage the PTO, turn the ignition key to off, and remove the key. 3. Wait for all moving parts to stop before leaving the operating position and then chock or block tires. 4. Clean around the oil dipstick (Fig. 27) so that dirt cannot fall into the filler hole and damage the engine. 1 m–7453 2 Figure 28 1 1. Oil drain plug 7. When oil has drained completely, close the oil drain.
Checking the Spark Plugs 3. Apply a thin coat of new oil to the rubber gasket on the replacement filter (Fig. 29). 1. Look at the center of the spark plugs (Fig. 31). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means that the air cleaner is dirty. 4.
Cleaning the Cooling System 5. Install air intake screen, recoil starter and fan housing. 5 Service Interval/Specification 3 Before each use, check and clean the engine cooling system. Remove any buildup of grass, dirt or other debris from the cylinder and cylinder head cooling fins, air intake screen on flywheel end, and carburetor-governor levers and linkage.
2. Lubricate the transmission couplers after every 100 operating hours and the idler bracket pivots after every 8 operating hours (Fig 35). 2. The rear wheels should lock when you try to push the machine forward or backward. Adjust the brakes if the wheels turn and do not lock. Refer to Adjusting the Brakes, page 32. 3. Release the brakes and move the neutral/brake locks to the Neutral position. Move the machine slightly, approximately 1/2 in. (13 mm). The wheels should rotate freely. 4.
Draining the Fuel Tank Servicing the Fuel Filter Service Interval/Specification Danger Replace the fuel filter after every 200 operating hours or yearly, whichever occurs first. 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. Replacing the Fuel Filter Important Never install a dirty filter if it is removed from the fuel line. • Drain gasoline from the fuel tank when the engine is cold.
Replacing the Traction Belt 1. Disengage the blade control (PTO) lever and set the parking brakes. 2 2. Stop the engine and wait for all moving parts to stop before leaving the operating position. 3 3. Raise the rear of the machine and hold it up with jack stands. 1 4. Remove the mower belt (Fig. 40). 4 m–5372 1 2 Figure 39 1. Drive belt 2. Drive spring 3. Tire 4. Adjustment bolt 3 4. Remove the drive belt from the pulleys and over the tire. 5 6 5. Install the new belt and the drive spring.
4. Remove the idler pulley and the worn belt (Fig. 40). 10. Remove the hairpin cotter and the clevis pin from the bell crank. 5. Install the new mower belt. 11. Rotate the clevis clockwise on the rod to increase the clearance; rotate it counterclockwise to decrease it (Fig. 42). 6. Install the idler pulley. 7. Engage the blade control (PTO) lever and check the belt tension. Refer to Adjusting the Mower Belt Tension, page 35. 12. Disengage the blade control (PTO) lever.
Adjusting the Grass/Mud Scraper 3. Loosen the locknut on the turnbuckle (Fig. 43). 4. Rotate the turnbuckle toward the rear of the mower to increase the tension on the belt. Rotate the turnbuckle toward the front of the mower to decrease the tension on the belt (Fig. 43). 1. Loosen the locknut that holds the scraper to the engine frame (Fig. 45). Note: The eyebolt threads on both ends of the turnbuckle should be engaged a minimum of 5/16 inch (8 mm). 3 2 Adjusting the Blade Brake 1.
