To change the oil, first run the engine for a few minutes to warm it up. Then turn off the mower and disconnect the spark plug. Place an oil pan under the drain plug, remove the plug, and let the oil drain completely. Replace the drain plug and refill with the recommended oil type and capacity.
Use high-lift blades for bagging, medium-lift blades for side discharge, and mulching blades if you want to mulch the grass clippings. Always ensure the blades are compatible with the mower model.
Check if the fuel tank has fresh gasoline and the fuel valve is open. Ensure the spark plug is connected properly and not fouled. Verify that the battery is charged if the mower is electric start. Also, inspect the air filter for any clogs.
Perform a general inspection before each use, change the engine oil every 50 hours, check the air filter every 25 hours and replace it if needed, and sharpen or replace blades as necessary. Conduct a comprehensive check and service annually.
To adjust the cutting height, locate the height adjustment levers on each wheel. Move the levers to the desired height setting, ensuring all wheels are set equally for an even cut.
Check if the blades are balanced and not damaged. Ensure that all bolts and screws on the deck are tightened. Inspect the spindle and pulleys for wear and replace them if necessary.
After each use, scrape off grass clippings and debris from the deck using a scraper or hose it down with water. Be sure to disconnect the spark plug before cleaning to prevent accidental starts.
Turn off the mower and disconnect the spark plug. Remove the mower deck and locate the drive belt. Release the tensioner and slide the belt off the pulleys. Install the new belt, ensuring it is seated correctly on all pulleys, and reassemble the mower deck.
Sharpen the blades after every 25 hours of use or if you notice uneven cutting or torn grass tips. Frequently mowing over rough terrain may necessitate more frequent sharpening.
Possible causes include a clogged air filter, stale gasoline, or a dirty carburetor. Check and clean the air filter, ensure fresh fuel is used, and clean the carburetor if needed. Also, check the spark plug for fouling.
