Can a riding mower overheat?

When a riding lawn mower overheats, it sometimes stops running or fails to restart once it is turned off.

Why does my riding mower stop running when it gets 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.

Why does my lawnmower smoke?

A lawn mower engine will puff out black smoke when the fuel and air mixture is too rich. Because there isn’t enough air, combustion is incomplete, and the unburnt fuel in the combustion chamber turns to smoke. You see the same phenomenon when you burn leaves and pack them too tightly to allow air to circulate.

How long does it take for a lawnmower engine to cool?

Typically, a ten-to-thirty second idling period is enough to aid in engine cool down. Letting your motor idle too long can cause the oil and engine to heat further, causing a slower cool down time. Idling has several definitions depending on who you ask or which lawn mower manual you read.

Do small engines need coolant?

All engines have a cooling system. Small engines use the air as a coolant and have some type of fan that moves the air over cooling fins. There are air cooled vehicles still on the road today that have no water filled radiator or water pump.
