Abstract: A method and apparatus for wrapping a protective cover about a bale. The bale is supported stationary on a tined lift of a vehicle and provided within a frame having a roll of a protective cover rotatable about a substantially horizontal axis. The roll of protective cover orbits about the bale for at least one complete revolution and protective covering is withdrawn from the roll onto the bale during the revolution. Thereafter, the protective cover is severed, and the wrapped bale is withdrawn from the frame. The time required to load and unload the bale from the wrapping machine is minimized since the bale is engaged by the tined lift of the tractor throughout the entire operation.
