Removing and Installing the Engine Hood Side Discharge The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 1. To remove the hood, loosen the knobs and then pull the hood back and up (Fig. 15). 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.
Tips for Mowing Grass Long Grass Fast Throttle Setting If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. For best mowing and maximum air circulation, operate the engine at the Fast position.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Each use After first 5 hours Maintenance Procedure • Check the engine oil level. • Check the safety system. • Clean the mower housing. • Change the engine oil.

Important worn. 2 1 Replace the foam element if it is torn or Cleaning the Paper Element: 1. Lightly tap the element on a flat surface to remove dust and dirt. 2. Carefully clean the rubber seal on the paper element to prevent debris from entering the engine. 3. Inspect the element for tears, an oily film, and damage to the rubber seal. Important Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene.
1 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. 2 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.
Warning 2 A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. 1 3 • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of blade. m–151 Figure 25 1. Cutting edge 2. Curved area 3. Wear/slot forming Removing the Blades Checking for Bent Blades The blades must be replaced if a solid object is hit, if the blade is out of balance, or the blade is bent.
4. Connect a grease gun to the fitting. Pump grease into the fittings until grease begins to ooze out of the bearings. 1 5. Wipe up any excess grease. m–1854 Figure 28 Where to Add Grease 1. Sharpen at original angle Lubricate the grease fittings as shown on the Check Service Reference Aid decal (Fig. 30) located beneath the seat. 2. Check the balance of the blade by putting it on a blade balancer (Fig. 29). If the blade stays in a horizontal position, the blade is balanced and can be used.
terminals are corroded, clean them with a solution of four parts water and one part baking soda. Apply a light coating of grease to the battery terminals to prevent corrosion. 3 2 Voltage: 12 v 1 Removing the Battery 5 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.
2. Check the electrolyte level; refer to Checking the Electrolyte Level, page 26. 2. Look at the side of the battery. The electrolyte must be up to the Upper line (Fig. 33). Do not allow the electrolyte to fall below the Lower line (Fig. 33). 3. Make sure that the vent caps are installed in the battery. Charge the battery for 1 hour at 25 to 30 amps or 6 hours at 4–6 amps. Do not overcharge the battery. 1 4.
4. Loosen the hose clamp at the fuel filter and slide it up the fuel line away from the fuel filter (Fig. 35). 6. Install a new filter and move the hose clamps close to the filter (Fig. 35). 5. Pull the fuel line off of the fuel filter (Fig. 35). 7. Open the fuel shut-off valve. Checking the Tire Pressure Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Adjusting the Front-to-Rear Blade Slope 5. Carefully rotate the blade(s) side to side (Fig. 37). Measure between the outside cutting edges and the flat surface (Fig. 37). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; refer to steps 6 through 8. 1 Check the front-to-rear blade level any time you install the mower. If the front of the mower is more than 5/16 inch (7.
9. Measure from the tip of the front blade to the flat surface and the tip of the rear blade to the flat surface (Fig. 40). If the front blade tip is not 1/16–5/16 inch (1.6–7.9 mm) lower than the rear blade tip, adjust the front locknuts. 1 1 2 2 m–6427 3 2 1 1 3 2 4 m–4634 3 Figure 41 1. Locknut and adjusting nut 2.
