Why Does My Mower Not Start When Hot

Air leaks cause an engine to pull in too much outside air, which throws off the gasoline-to-air ratio. As the engine heats, parts expand, and all tiny gaps become larger. The result is a poorly running engine and one that eventually stops. Loose bolts are a common culprit in a mower engine that shuts down when hot.

What happens when a lawn mower overheats?

When a riding lawn mower overheats, it sometimes stops running or fails to restart once it is turned off. Running an overheated mower for long periods can cause damage to the engine’s internal components. When the engine overheats, shut it down and correct the cause of the problem before continuing to run the mower.
