Perform regular maintenance by checking and replacing the engine oil, inspecting the air filter, cleaning the mower deck, sharpening the blades, and checking tire pressure. Refer to the owner’s manual for a detailed maintenance schedule.
If the mower won't start, check the fuel level, ensure the battery is charged, inspect the spark plug, and verify that the safety switches are engaged. If the problem persists, consult the manual or contact a professional.
To troubleshoot uneven cutting, check the tire pressure, ensure the deck is level, inspect the blades for damage, and make sure the blades are properly installed and sharpened.
The recommended oil type is SAE 30 or 10W-30 for temperatures above 32°F (0°C). Always check the owner’s manual for specific recommendations based on your operating conditions.
To change the blades, first disconnect the spark plug, raise the mower deck, use a wrench to remove the blade bolt, replace with a new blade, and tighten the bolt securely. Ensure safety measures are in place.
If the mower deck vibrates excessively, check for debris lodged in the deck, inspect the blades for balance and sharpness, and ensure all mounting bolts are secure. Consider consulting a professional if the issue continues.
Replace the air filter every 100 operating hours or annually, whichever comes first. Check more frequently if you operate in dusty conditions. Always refer to your owner's manual for specific guidance.
To store the mower for winter, clean the mower deck, change the oil, add fuel stabilizer to the tank, remove the battery, and store it in a dry, safe place. Cover the mower to protect it from dust and moisture.
To adjust the cutting height, locate the height adjustment levers on the mower deck, and move them to your desired height setting. Ensure both sides are set equally to maintain an even cut.
Streaks of uncut grass may be caused by dull blades, an unlevel deck, or mowing too fast. Sharpen the blades, check deck alignment, and reduce speed if necessary.
