To start the Toro Recycler 21-inch 21320 Mower, ensure the fuel valve is open, the throttle is set to 'choke' if the engine is cold, and the blade control bar is engaged. Then, pull the starter handle briskly.
If the mower is hard to start, check the fuel level and quality, ensure the spark plug is clean and properly connected, and inspect the air filter for clogs. Replace any damaged components as necessary.
To adjust the cutting height, locate the height adjustment levers on each wheel and move them to the desired position. Ensure all four wheels are set at the same height for an even cut.
Use SAE 30 or SAE 10W-30 motor oil for the Toro Recycler 21-inch 21320 Mower, depending on the temperature range in your region. Refer to the owner's manual for specific recommendations.
To enhance mulching performance, ensure the blade is sharp and the underside of the deck is clean. Mow when the grass is dry and adjust the mowing height as needed to avoid overloading the engine.
The air filter should be checked every 25 hours of use and replaced if it appears dirty or damaged. Regular maintenance helps ensure optimal engine performance.
Perform regular maintenance such as checking the oil level before each use, changing the oil every 50 hours, inspecting the blade for sharpness, and servicing the air filter every 25 hours. Follow the owner's manual for detailed guidance.
To clean the mower deck, first disconnect the spark plug wire for safety. Use a garden hose to wash away grass clippings and debris. Avoid using a pressure washer as it may damage components.
Excessive vibration can be caused by a damaged or unbalanced blade. Inspect the blade for bends or damage, and replace it if necessary. Ensure the blade is securely tightened to the spindle.
To winterize the mower, run the engine until it stops to empty the fuel system, change the oil, remove the spark plug and add a few drops of oil into the cylinder, and clean the mower thoroughly before storing it in a dry location.
