PROBLEM TO BE SOLVED: To solve problems, where the work of furrowing the subsoil and improving soil layers between ridges is required for sugar cane production because of the treading pressure exerted by a large harvester in harvesting; however, a ground surface is ordinary covered with a large amount of residual material for the prevention of weeds growth and when the work for furrowing the subsoil and improving soil layers is performed, the ground surface has to be kept unexposed and the damage to new sprouts by thrown soil clumps must be avoided but if the residual material entwines a working machine, the residual material is mixed with soil and forms lumps, causing the increase of traction resistance and leading to the ground surface exposure which is caused by the movement of the residual materials dragged by the lumps. SOLUTION: The efficiency in the work of furrowing the subsoil and improving soil layers is enhanced by: attaching a divided claw having a blade to the middle part of a plow body of the working machine in a manner inclined forward and extended to the frame position; lifting the residual materials between ridges by converting the subsoil throwing energy to a ground surface lifting energy; and thrusting the residual materials with the forwardly inclined divided claw having a blade to separate out and to divide without entwining.
