Clutcher is a term used in the automotive industry to describe a device that uses a CLAW-like mechanism to engage and disengage a rotating shaft. It is commonly used in manual transmissions, where it is used to connect the engine to the transmission. The clutch is an important part of the transmission system, as it allows the driver to control the power output of the engine and the speed of the vehicle. Clutchers are also used in other applications, such as in industrial machinery and in some types of pumps.
