First, ensure the mower is turned off and on a flat surface. Use a socket wrench to remove the blade bolts. Carefully remove the old blades and replace them with new ones, ensuring they are properly aligned. Tighten the bolts securely.
Check the fuel level and ensure the fuel valve is open. Inspect the battery connections for corrosion and ensure they are secure. If the engine still doesn't start, check the spark plug for wear or damage and replace if necessary.
Regular maintenance should be performed at least once per mowing season, including checking the oil, air filter, blades, and belts. A comprehensive check should be done annually.
Toro recommends using SAE 30 or 10W-30 oil for the Wheel Horse 60-inch 78390 Mower, depending on the climate conditions. Refer to the user manual for specific temperature guidelines.
Check that the tire pressure is even on all wheels. Inspect the mower deck to ensure it is level. Additionally, examine the blades for sharpness and replace or sharpen if necessary.
After ensuring the mower is off and cool, use a garden hose to spray off grass clippings from the deck. For stubborn debris, a scraper or brush can be used. Ensure the underside is dry before storing to prevent rust.
Locate the height adjustment levers on each wheel or the central lever depending on the model. Move the lever to the desired cutting height position, ensuring all wheels are set to the same height for even mowing.
Check for debris stuck in the blades or mower deck. Inspect the blades for balance and alignment. Also, check the engine mounting bolts and all pulleys for tightness.
Clean the mower thoroughly, change the oil, and add a fuel stabilizer to the tank. Disconnect the battery and store it in a cool, dry place. Cover the mower to protect it from dust and moisture.
The serial number is typically located on a tag under the seat or on the frame near the engine. Refer to the owner's manual for the exact location on your model.
