ABSTRACT:
Interactive component parts for assembling an ATV-mounted hunting stand of either the "A"-frame type or tree-leaning type, or alternatively as a ground-standing tree-leaning hunting stand. It includes a leveling seat platform, ladder elements, quick-grasping base connector assemblies, and a ground support. The seat platform has angularly-adjustable sockets so sized as to fit onto the upper ends of ladder elements, whose lower ends may have sleeves to allow these ladder elements to be mounted atop other ladder elements. Base connector sleeve assemblies allow ladder elements to be quickly and easily mounted on and demounted from rods attached to an ATV; they are free to pivot about these rods. When such ladder elements are so mounted on an ATV as an A-frame hunting stand, changing the angularity of the seat sockets effects seat leveling. For ground-standing ladder use, a broad ground support may be inserted into the lowest ladder element.
