The round bale wrapping machine is tractor operated and is equipped with a rotatable platform to support the bale in an upright position for rotation about a vertical axis. The machine supported bale is located adjacent a wrapping mechanism which automatically wraps a plastic sheet material about the bale under the control of the tractor operator. The plastic sheet material is of a roll form rotatably carried on an upright arm at a fixed location on the machine frame. The wrapping mechanism is movably supported on the machine frame for selected movement with and relative to the rotatable platform and to the plastic roll and operates to automatically complete a first plastic wrap around the bale with the lead end of the plastic sheet pressed against the bale periphery at a position to be covered by a second wrap of the plastic sheet about the bale. On completion of the second wrap, the plastic sheet is automatically severed concurrently with the retention or holding of the resulting or new lead end of the plastic roll in a position to first wrap a next bale. The wrapped bale is then removed from the machine and ground supported on the side thereof having the overlapped terminal ends of the two plastic wraps.
