PURPOSE:To make it possible to easily move a machine on the road, by providing a lever for changing over slidable gears in a mission casing to transmit the engine side rotational power alternatively to a plowing shaft or running wheels. CONSTITUTION:In order to drive a plowing shaft 21, a lever provided to a mission casing is manipulated to transmit the rotational power of the engine 4 side to a plowing shaft 21, and therefore, the machine plows the land while it is propelled by itself. Further, in order to move on the road, the lever is shifted so that the rotational power is transmitted to running wheels 29. Then, the plowing shaft 21 is not rotated, completely, while the running wheels 29 are alone rotated. In this case the steering wheel of the power farm machine is depressed to float up the plowing shaft 21 so that the machine is steered by means of the steering wheel, and therefore, the machine is smoothly moved forward or backward, thereby it is possible to facilitate the travel of the machine.
