To start your Toro Recycler 55-cm 21766 mower, ensure the fuel tank is filled and the oil level is adequate. Press the primer bulb three times, then pull the recoil starter firmly to start the engine.
Use SAE 30 oil for optimal performance in temperatures above 40°F (4°C). For temperatures below 40°F, use SAE 10W-30 for better cold-start capability.
It is recommended to sharpen the mower blades after every 20-25 hours of use to maintain cutting efficiency and ensure a clean cut.
If your mower won't start, check the fuel level, ensure fresh fuel is used, inspect the spark plug for wear, and verify that the air filter is clean.
Adjust the cutting height by moving the height adjustment lever on each wheel to the desired position. Ensure all wheels are set to the same height for an even cut.
Excessive vibration can be caused by an unbalanced blade or debris lodged in the mower deck. Inspect the blade for damage and clear any debris from the deck.
To replace the spark plug, disconnect the spark plug wire, remove the old spark plug using a socket wrench, and install a new one. Make sure it is tightened to the manufacturer's specifications.
Remove the air filter cover, take out the filter, and gently clean it with soap and water. Allow it to dry completely before reinstalling. Replace if it is damaged.
To winterize your mower, run it until the fuel is depleted, clean the deck, and remove any debris. Change the oil and spark plug, and store in a dry place.
At the start of the season, change the oil, replace the spark plug, clean or replace the air filter, and inspect the blades for sharpness and balance.
