Abstract
The invention relates to an arrangement and method for operating a self-propelled vibratory plate device. The vibratory plate of this device receives its vibratory motion from counter-rotating eccentric parts driven by an internal combustion engine. According to the method, the vibratory plate is stopped with a deadman's handle mounted on the device without the engine stopping. The method is realized with the arrangement of the invention which includes the deadman's handle. The deadman's handle is connected to the engine's fuel control and a centrifugal clutch between the engine and the eccentric parts is engaged only when the speed of the engine is above idle speed. A cam is provided with an interacting support which limits the angular movement of the deadman's handle to a position which corresponds to the idle speed of the engine.
