ABSTRACT:
A pole ladder folding deer stand is formed by upper and lower tubular sections hingedly joined in aligned relation and provided with vertically staggered steps for ascending and descending the pole ladder. A seat and backrest assembly hingedly connected with the upper limit of the upper pole section projects horizontally toward a tree and includes a yoke and strap assembly for joining the seat assembly to a tree. A foot platform is horizontally supported above the uppermost step forwardly of the position of the seat assembly. A ladder stabilizing engaging yoke projects laterally from the respective sides of the ladder lower section at its depending end. A bicycle fork journals a wheel attachable to one of the ladder sections to permit wheelbarrow-like movement of the folded ladder tree stand for transporting equipment or game.
