摘要： PROBLEM TO BE SOLVED: To provide a self-propelled root crop harvester for digging a root crop out of soil covered with a mulching film, pulling and transferring the crop and storing in a storing container while preventing the drawing of the mulching film in the dragging of the leaf of the root crop. SOLUTION: In case of pulling out a root crop cultured on a ridge covered with a mulching film 70, the mulching film is liable to be lifted together with the root crop at the pulling out of the crop with the starting end of a conveyor B and dragged to the conveyor. The problem is solved by placing a mulching film pressing roller 65 under the front end of the dragging conveyor to effect the transfer of exclusively the root crop backward with the dragging conveyor in the clamping of the leaf of the crop at the front end of the dragging conveyor and the transfer of the crop upward to the back.
