  • Patent number: 5482120
    Abstract: Apparatus and method for pulling plant stalks from the ground without severing the stalk at the point of engagement. The pulling action is accomplished with pairs of disks configured to engage the other near each's circumference. An upward pulling action is created by the disks because the disks initially come together, pinching the stalks therebetween, at a lower most position. As the disks roll in response to their traversing movement across the ground and the cleat's engagement with the ground, the pinch point between the disks and the stalk revolves upward producing a pulling action upon the stalk. The advantageous pulling action of the invention is accomplished in part by the novel orientation of the disks, one to the other, and the angles of engagement between the disks, the stalks and the ground during operation.
