A portable round bale wrapping apparatus which wraps large upright cylindrical straw bales with protective plastic film for storage on the field. One person can operate the wheeled bale wrapper on uneven ground. A light-weight tubular frame with a pulley system moves the wrapper roll up and down. The rotation of wrapping can be reversed by moving the pulley system to an opposite side . The wrapping apparatus can be adjusted in height and length to accommodate the variance in size of hay or straw bale. The bale wrapping apparatus can be dismantled, folded into a light-weight package and carried to the next field or stored.
