When the transport work cart having the digger of the present invention and the independent drive means is introduced into the field at the start of the excavation of a long fence or the like, the transport work cart is separably connected to the side of the digging portion. Since no headland for the length is required, there is no dead space that cannot be dug. In addition, since the transport work cart has a self-supporting drive configuration, if it is driven autonomously on a sloped field, it can help drive without relying on the traction force of the towing tractor and continue the harvesting transport work. In a farm with no hills, it is possible to drive lightly and economically by towing neutrally. In addition, since it can be operated from the work table, it is convenient that a self-sustained drive separation operation can be performed immediately when the slope is tight during the work or when the soil excavation load increases. Since the mounting table protrudes and is a soft roller, the long wall dug up is not damaged, and each roller is released, so the soil peeled off from the long wall falls directly on the ground surface and accumulates on the mounting table to disturb There is no. Since the independent drive means has a continuously variable transmission, it can easily cope with the speed of the traction tractor. In addition, since the traction point of the transport cart connected to the machine frame of the digging portion is set at the substantially center with respect to the width direction of the transport cart, the tow center of the transport cart is driven in parallel and stabilized. .
