PROBLEM TO BE SOLVED: To provide a configuration of a new digging device, capable of performing deep tillage even to clayey arid soil newly reclaimed from existing farmland planted with the same crop every year or special field soil quality embedded with volcanic rock.SOLUTION: A partial deep tillage rotary device for long-diameter root crops connected to a tractor comprises: a main transmission box vertically movably mounted to a rear part of the tractor through a link mechanism, performed with input from the tractor, and provided with transmission cases; and deep tillage dipping parts driving rotary flanges by output shafts provided in the transmission cases. The deep tillage dipping part is disposed with a cylindrical narrow large-diameter drum body concentric with the output shaft, and a lot of columns of cut claws are fixed to the outer circumferential face of the drum body. |
