To change the blades, first ensure the mower is off and the spark plug is disconnected. Lift the mower deck and secure it. Use a wrench to remove the blade bolts. Replace with new blades, ensuring they are installed correctly and tightened securely.
For optimal performance, use high-quality SAE 30 detergent oil for temperatures above 32°F (0°C). Below 32°F, use SAE 10W-30 or 5W-30. Always check the engine oil level before each use.
If the mower doesn't start, check the fuel level and quality, ensure the spark plug is intact and clean, and the battery is charged. Verify that the safety switches are engaged and the mower deck is disengaged.
Sharpen the mower blades every 25 hours of use or at least once per mowing season. Dull blades can tear grass, causing lawn stress and an uneven cut.
Excessive vibration can be caused by unbalanced blades, loose bolts, or debris lodged in the mower. Inspect and balance the blades, tighten any loose components, and clear debris from the deck.
To store the mower for winter, clean the deck and undercarriage, change the oil, and drain the fuel tank or add a fuel stabilizer. Disconnect the battery and store it in a cool, dry place. Cover the mower to protect it from dust and moisture.
The recommended tire pressure is typically between 10-15 psi for the rear tires and 12-15 psi for the front tires. Check the tire sidewall or owner's manual for exact specifications.
To improve cut quality, ensure the blades are sharp, the deck is clean, and the tire pressure is even. Adjust the deck height according to the grass type and condition. Mow only when the grass is dry.
Uncut strips can be caused by dull blades, incorrect deck leveling, or mowing too fast. Sharpen the blades, check and adjust the deck level, and reduce mowing speed for a cleaner cut.
To adjust the cutting height, use the height adjustment lever or knob on the mower deck. Ensure both sides of the deck are set to the same height for an even cut. Refer to the owner's manual for specific instructions.
