  • Method and apparatus for wrapping round bales
    Patent number: 4827700
    Abstract: An apparatus for wrapping round hay bales includes an upstanding post having means for mounting to a three-point hitch attached to a lower end and a generally horizontally extending dispensing arm pivotally attached to an upper end. An elongated spindle is rotatably mounted on the post for engagement with a round hay bale along its longitudinal axis. A spinner plate is also rotatably mounted on the post and includes prongs for engaging an end of the hay bale. An hydraulic motor is provided for rotating the spinner plate which in turn rotates the hay bale on the spindle. An hydraulic cylinder and linkage is connected to the dispensing arm for rotating the arm and maintaining a sheet material dispenser assembly attached to the arm in a predetermined relation to the longitudinal axis of the bale to helically wrap sheet material on the exterior of the bale.
