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.

1 Side Discharging or Mulching the Grass 2 Danger 6 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 blades and thrown debris will cause injury or death. 6 5 5 3 • Never remove the grass deflector from the 4 m-1883 Figure 14 mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.
• If you must stop the tractor while mowing, you may leave a clump of grass clippings on your lawn. To avoid this, do the following: • Use the washout port to clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, the cutting quality will eventually become unsatisfactory. – Engage the blade and move to a previously cut area. • Maintain a sharp blade throughout the season.
Important Refer to your engine operator’s manual for additional maintenance procedures. Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and 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 Engine Oil 1 Check the oil level daily or after every 8 hours.
3. Disengage the blades (PTO). 4. Install the replacement oil filter to the filter adapter. Turn the oil filter clockwise until the rubber gasket contacts the filter adapter; then tighten the filter an additional 1/2 to 3/4 turn (Fig. 17). 4. Set the parking brake. 5. Stop the engine and wait for all moving parts to stop. 5. Slowly pour approximately 80% of the specified amount of oil into the fill hole (Fig. 15). Check the oil level; refer to steps 8 and 9 of Checking the Oil Level on page 20. 6.
