Abstract
A pressure washer is provided. The pressure washer can include a frame and a power source coupled to the frame. The power source can include an output shaft. The pressure washer can include a centrifugal clutch. The centrifugal clutch can include an input portion operably coupled to the output shaft and an output portion. The input portion of the centrifugal clutch can be operable to be selectively coupled to the output portion. The pressure washer can include a pump assembly, which can include a pump mechanism operably coupled with the output portion of the centrifugal clutch to pressurize a fluid when the input portion of the centrifugal clutch is coupled to the output portion. The pressure washer can also include an actuator in communication with at least the power source to actuate the power source to drive the output shaft.
