Use SAE 30 oil for general use in temperatures above 32°F. If operating in temperatures below 32°F, use SAE 5W-30 oil. Always check the owner’s manual for specific guidelines.
To start the mower, ensure the fuel valve is open, press the primer bulb three times if the engine is cold, pull and hold the blade control bar against the handle, and then pull the starter handle quickly.
Sharpen the mower blade at least once per mowing season or after every 25 hours of use. If you notice uneven cutting or tearing of grass, it may be time to sharpen the blade.
Check the fuel level, ensure the fuel valve is open, verify the spark plug is connected and not fouled, and ensure the air filter is clean. If issues persist, consult the troubleshooting section of the manual.
After use, allow the engine to cool, then use a garden hose to rinse off grass clippings and dirt from the undercarriage. Be sure to avoid spraying water directly into the engine or other electrical components.
Adjust the cutting height by using the height adjustment levers located on each wheel. Ensure all four levers are set to the same position for an even cut.
Perform an oil change every 25 hours of operation or at least once per season. Clean or replace the air filter annually, and inspect the spark plug every 100 hours or annually. Regularly check for loose or damaged parts.
To winterize the mower, drain the fuel tank or add a fuel stabilizer, change the oil, remove the spark plug and add a tablespoon of oil into the cylinder, then pull the starter handle to distribute it. Store the mower in a dry place.
Excessive vibration may be caused by a damaged blade or loose parts. Inspect the blade for damage and ensure all bolts and fasteners are secure. Replace the blade if necessary.
Yes, the Toro Recycler 21-inch 20531 Mower is equipped with a mulching feature and a bagging option. Switch between modes by changing the position of the mulch plug and attaching or removing the grass bag.
