Abstract: Apparatus for modifying conventional automatic three table bale wagons handling small bales to load, transport, and stack big bales with dimensions in excess of 3 feet×4 feet ×8 feet. With the apparatus a modified bale wagon picks up and handles big bales during traversal of a field in which big bales of vegetative material have been deposited. The modified bale wagon with its apparatus loads the big bales one at a time and orders them without rotation, two at a time, on a loading table of a conventional three table automatic bale wagon which pivots vertically, placing the two big bales on end on the bale wagon load bed side-by-side in the bale wagon load bed. When the load bed reaches capacity, six to eight big bales, the bale wagon is driven to a storage area where the load bed pivots 90°, allowing the big bales to be pushed off the load bed, forming a compact stack of six to eight big bales.
