• Adjust throttle settings: Once the engine starts, adjust the throttle to an appropriate operating speed. Refer to the owner’s manual for recommended throttle settings.

Avoiding Overloading Or Overworking The Mower

Overloading or overworking your Toro lawn mower can lead to engine strain and, ultimately, failure to stay running.

Here are some points to consider:

• Mowing height: Adjust the mower’s cutting height within the recommended range for your specific grass type and conditions. Cutting too low or too high can strain the engine and potentially cause it to stall.
• Mowing speed: Avoid mowing at excessively high speeds. Maintain a steady and consistent pace that allows the mower to effectively cut the grass without straining the engine.
• Manage thick grass or debris: If you encounter thick grass or excessive debris, consider slowing down or making multiple passes to prevent overloading the mower. Clear any large debris from the mowing area to avoid potential damage to the blade or engine.
• Avoid excessively long grass: Cutting excessively long grass in a single pass can put undue strain on the engine. Gradually decrease the cutting height and make multiple passes until reaching the desired height.
