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.

Method for operating a self-propelled vibratory plate device equipped with a control handle and a deadman\s handle to stop the motion of the vibratory plate, forward or backward, the plate receiving its directional vibratory motion from counter-rotating eccentric parts, driven by an internal combustion engine via a centrifugal clutch, the centrifugal clutch starting to operate only when the engine speed is above idle speed, the deadman\s handle being rotatably mounted on the device for rotating between an uplifted position, a drop position and a stop position, the method comprises the steps of stopping the internal combustion engine, setting the engine to idle speed, and setting the engine to working speed with only a single control in the form of the deadman\s handle mounted adjacent the control handle of the device and connected to the fuel control of the engine so that the engine runs at idle speed when the deadman\s handle is inactive or in the drop position.
