To adjust the cutting height, locate the height adjustment levers on each wheel. Move the levers to the desired height setting, ensuring all four wheels are set to the same level for an even cut.
If the mower does not start, check the fuel level, ensure the spark plug is connected, and verify that the safety switch is engaged. Additionally, inspect the air filter for dirt or obstructions.
Blades should be sharpened after every 20 to 25 hours of use or at the beginning of each mowing season to ensure a clean and healthy cut.
It is recommended to use SAE 30 oil for temperatures above 32°F (0°C) and 10W-30 oil for temperatures below 32°F (0°C).
To replace the drive belt, disconnect the spark plug, remove the deck, and release the belt from the pulleys. Install the new belt around the pulleys, ensuring it is properly seated, then reattach the deck.
Clean the mower thoroughly, remove any fuel, and store it in a dry, sheltered location. Cover the mower to protect it from dust and debris.
Check that all wheels are set to the same height, inspect the blades for sharpness and damage, and ensure the deck is level. Adjust as necessary for even cutting.
Excessive vibration may be caused by unbalanced or damaged blades. Inspect the blades and replace or balance them as needed. Additionally, check for loose bolts and components.
Remove the air filter cover, take out the filter, and clean it with warm soapy water. Let it dry completely before reinstalling. Replace the filter if it is damaged or excessively dirty.
Regular maintenance includes checking and changing the oil, sharpening the blades, cleaning the air filter, inspecting the spark plug, and checking the tire pressure. This should be done at least once per season.
