ABSTRACT:
A combination tree seat and animal drag device includes an elongated central support having a first end and a second end and an elongated cross support attached to the first end of said central support and extending approximately transverse thereto. The central support and cross support together form a substantially T-shaped frame member. A seat member is removably attached to a planar surface of said frame member. Tree grip means are provided on the second end of said central support. An elongated strap is removably attached at each end thereof to an attachment means at the ends of the cross support. The frame member may be attached to a tree by engaging the grip means on the central support with an outer surface of the tree and passing the strap around the tree and attaching the strap to the attachment means on the cross support.
