  • Delivery tray return mechanism for a bale wagon
    Patent number: 4305690
    Abstract: A bale wagon for picking up bales of crop material from the field and forming them into a generally symmetrical pyramidal stack for deposit at a selected location is provided. The bale wagon includes a mobile frame pivotally supporting a stack forming load bed, a bale support and transfer mechanism for depositing the bales at a predetermined position on the load bed, a pickup mechanism for moving the bales from the field to the support and transfer mechanism, and a pusher mechanism for moving the bales along the load bed from the predetermined position. A control mechanism coordinates the functioning of the components so as to form a multi-layered stack of bales with each succeeding layer centered on and containing one less row of bales than the previous layer.
