Toro Wheel Horse 42-inch 05-42SY03 Operator's Manual

To change the blade, first ensure the mower is turned off and the spark plug is disconnected. Tilt the mower to access the blade. Use a wrench to remove the bolt securing the blade, then replace it with a new one. Tighten the bolt securely and reconnect the spark plug.
For optimal performance, use SAE 30 motor oil for temperatures above 32°F (0°C), and 10W-30 for variable temperature ranges. Always check the owner’s manual for specific recommendations.
Check the fuel level and ensure fresh fuel is used. Verify the spark plug is clean and properly connected. Inspect the air filter for dirt or blockage. If the mower still doesn’t start, consult the manual for detailed troubleshooting steps.
Perform a routine check before each use, including oil level checks and blade inspection. Change the oil every 50 hours of operation or annually. Replace the air filter and spark plug annually or as needed. Refer to the manual for a detailed maintenance schedule.
To adjust the cutting height, locate the height adjustment lever on the side of the mower. Move the lever to your desired cutting height position. Ensure both sides are adjusted equally for an even cut.
Excessive vibration may be caused by a damaged or unbalanced blade. Inspect the blade for damage and replace if necessary. Check for debris buildup under the deck and clean it. Ensure all bolts and fasteners are tightened.
Keep the engine well-maintained, including regular oil changes and air filter replacements. Use fresh, clean fuel and ensure the tire pressure is correct. Regularly sharpen the mower blades to reduce engine load.
To winterize, drain the fuel tank or add a fuel stabilizer. Clean the mower, removing grass and debris. Change the oil and check the spark plug. Store the mower in a dry, sheltered location. Disconnect the battery if applicable.
Uneven cutting may be caused by a dull blade or incorrect deck level. Sharpen or replace the blade as needed. Check the tire pressure and adjust the deck level according to the manual’s instructions.
After each use, disconnect the spark plug and use a garden hose to rinse off the mower deck. For stubborn grass clippings, use a plastic scraper. Ensure the deck is dry before storing to prevent rust.
