Toro Whirlwind 20-inch 23017 Operator's Manual

To start the Toro Whirlwind 23017 Mower, first ensure the fuel tank is filled, the oil level is adequate, and the spark plug is connected. Then, hold the safety bar against the handle and pull the starter rope with a smooth, steady motion.
If the mower does not start, check the fuel level and freshness, confirm the spark plug is clean and connected, and ensure the air filter is clear. Additionally, make sure the safety bar is fully engaged while starting.
Blades should be sharpened at least once per mowing season, or more frequently if you notice uneven cutting or if the mower is used heavily. Regular sharpening ensures optimal cutting performance.
Use SAE 30 oil above 32°F (0°C) and SAE 5W-30 below 32°F (0°C). Ensure the oil is a high-quality detergent oil classified for service SF, SG, SH, SJ, or higher.
To replace the air filter, locate the air filter cover on the side of the engine, remove the cover, and replace the old filter with a new one. Ensure the new filter is properly seated before replacing the cover.
To improve cutting performance, regularly sharpen the blades, maintain proper tire pressure, and ensure the engine is running smoothly by keeping up with regular maintenance such as oil changes and air filter replacements.
Before winter storage, clean the mower thoroughly, remove any grass and debris, change the oil, empty the fuel tank or add a fuel stabilizer, and check the spark plug. Store the mower in a dry, protected area.
To adjust the cutting height, locate the height adjustment levers on each wheel, and move them to the desired position. Ensure all wheels are set to the same height for an even cut.
Excessive vibration can be caused by a damaged blade, loose parts, or debris caught in the mower. Inspect the blade for damage, tighten any loose components, and clear any debris from the mower deck.
After use, clean the mower by removing grass clippings and debris from the deck and wheels. Use a hose to rinse off dirt, but avoid spraying water directly onto the engine. Dry the mower thoroughly to prevent rust.
