Toro ProLine Recycler 21-inch 22142 Operator's Manual

To start the mower, first ensure the fuel valve is open and the engine switch is in the 'On' position. Then, press the primer bulb three times if the engine is cold. Finally, pull the starter handle briskly to start the engine.
Use SAE 30 oil for optimal performance in temperatures above 32°F. For temperatures below 32°F, SAE 5W-30 is recommended. Always check the oil level before each use.
Ensure there is fresh fuel in the tank and the fuel valve is open. Check the air filter for obstructions and ensure the spark plug is clean and properly connected. If issues persist, check the carburetor for clogs.
To clean the mower deck, ensure the engine is off and the fuel valve is closed. Tilt the mower on its side with the air filter facing up. Use a garden hose to rinse off grass clippings and debris. Avoid using high pressure to prevent damage.
The mower blade should be sharpened at least once per mowing season or more frequently if you notice uneven cutting or tearing of grass. Ensure the blade is balanced after sharpening.
Regular maintenance includes checking and changing the oil, cleaning or replacing the air filter, inspecting the spark plug, and sharpening the blade. Additionally, check for loose bolts and clean the mower deck after each use.
To enhance mulching, keep the mower blade sharp and mow when the grass is dry. Set the cutting height to remove no more than one-third of the grass blade length at a time. Ensure the deck is clean and free of debris.
Excessive vibration can be caused by a damaged or unbalanced blade, loose engine mounting bolts, or debris lodged in the mower deck. Inspect these areas and address any issues found.
To adjust the cutting height, locate the height adjustment levers on each wheel. Move the levers to the desired position, ensuring all wheels are set to the same height for an even cut.
If the mower leaves streaks, check if the blade is dull and needs sharpening. Ensure the deck is clean and the cutting height is set appropriately. Also, mow at a slower pace to ensure even cutting.
