What is a governor on a lawn mower and how does it work?
A governor on a lawn mower is a device that regulates the speed of the engine, preventing it from exceeding a certain limit. It works by controlling the amount of fuel that is delivered to the engine, which in turn affects the speed at which the engine runs. The governor is typically connected to the throttle and the carburetor, and it uses a combination of mechanical and centrifugal forces to regulate the engine speed. When the engine speed increases, the governor reduces the amount of fuel being delivered to the engine, which slows it down. Conversely, when the engine speed decreases, the governor increases the amount of fuel being delivered, which speeds it up.
The purpose of the governor is to prevent the engine from running too fast, which can cause damage to the engine and other components of the lawn mower. It also helps to improve the overall performance and efficiency of the lawn mower, by ensuring that the engine is running at the optimal speed for the task at hand. For example, when mowing thick or tall grass, the governor may reduce the engine speed to prevent the engine from bogging down.
