ABSTRACT:
A vine cutter for cutting entangled vines of potato plants in front of a potato harvester so that the vines do not become entangled and accumulated upon a front portion of the potato harvester. The inventive device includes a frame having a pair of upper members and a pair of opposing lower members, a first disc journaled to the frame, a second disc journaled to the frame below the first disc and having a ground engaging rim attached coaxially, and a motor mechanically connected to the first and second discs. The first disc and the second disc are vertically orientated, and a portion of the discs overlap and are juxtaposed to one another. The pair of discs preferably include a plurality of notches projecting into their respective outer perimeters. The discs rotate at a differential to one another from 1.2 to 2.5 depending upon the type of vines being cut. The ground engaging ring attached to the second disc determines the depth of penetration by the second disc into the ground. The discs preferably rotate opposite of one another with a lower portion of the second disc rotating with the movement of the frame with respect to the ground surface.
