ABSTRACT:
A hay bale wrapping machine having a platform having a forward end, opposite forward corners, opposite sides and a rearward end. Support wheels are located on opposite sides of the platform. A bale wrapping unit is mounted on the platform. A pair of arms are pivotally secured to the forward end of the platform and are connected to a power unit for pivoting the arms from a forwardly extending position to an upwardly and rearwardly position to permit a bale of hay secured between the arms to be lifted over the front end of the platform for operative positioning on the bale wrapping unit. A hydraulic unit connected to the arms permits them to be moved towards and away from each other for grasping and releasing, respectively, a bale. A tongue unit is pivotally secured to the side of the platform, and can be hydraulically moved to an angular position with respect to the direction of travel of the machine. A method of wrapping hay bales by moving the bale wrapping machine in a direction generally along the windrow in which the bales are resting on the ground; approaching the bales with the machine so that the forward end of the platform is generally parallel to the axis of the bale; then lifting the bale over the forward end of the platform and depositing the bale on the bale wrapping unit; and then wrapping the bale with a protective material.
