发明名称 Stump and pole extraction device
摘要 A device for extracting stumps and poles from the ground. The device includes a pair of legs each having an upper end and a lower end. A pivot pin, adapted to suspend a winch above the ground, hingedly joins the legs together at their upper ends. A pair of ground-engaging feet are secured to the lower ends of the legs and extend laterally therefrom. A flexible connector selectively connects the feet together and may be retracted into one of the legs.
