A wheeled attachment for a litter for transportation of a litter via a single operator. The wheeled attachment generally includes a traverse frame extending across one end of the litter, first and second receiver tubes pivotally connected to opposing ends of the frame, the first and second receiver tubes pivoting between a first position against the frame and a second position perpendicular with the frame to receive the handle ends of the litter, and including first and second wheels pivotally connected to opposing ends of the frame and coupled to the receiver tubes to also pivot between the first and second pivotal positions parallel to and perpendicular with the frame. The receiver tubes also include an opening and coupler assembly for fixing the handles within the respective coupler. The frame further preferably extends above the netting of the litter to provide a foot stop for the patient upon the litter.
