To start the Toro 21-inch 26643 Mower, ensure the mower is on a flat surface. Check the oil and fuel levels. Pull the safety bar towards the handle and pull the starter cord firmly.
If the mower won't start, check for fresh fuel, ensure the spark plug is connected, and inspect the air filter for clogs. If problems persist, consult the manual or contact a professional.
Sharpen the mower blade every 20-25 hours of use, or at the beginning of each mowing season, to ensure a clean cut and promote lawn health.
After use, disconnect the spark plug, use a hose to wash away grass clippings from the underside, and wipe down the exterior with a damp cloth. Dry thoroughly to prevent rust.
To improve performance on thick grass, raise the cutting height, mow more frequently, and ensure the blade is sharp. Mow when the grass is dry for best results.
Before storing, run the mower to empty the fuel tank, change the oil, clean the deck, and remove the battery if applicable. Store in a dry location.
To adjust the cutting height, locate the height adjustment lever near each wheel. Move the lever to the desired setting, ensuring all wheels are set to the same height.
Excessive vibration may be due to an unbalanced blade. Check for damage or debris on the blade, and ensure it's properly secured. Balance or replace the blade if necessary.
Change the oil after the first 5 hours of use, then every 25 hours or at the start of each mowing season for optimal engine performance.
Using the mower on wet grass is not recommended as it can lead to clumping and uneven cutting. Wait until the grass is dry for best mowing results.
