AUTOMATIC CONTROL LINKAGE FOR ROUND BALE WAGON ABSTRACT OF THE DISCLOSURE A control linkage for a round bale wagon is disclosed wherein the operation of the mechanism for conveying bales laterally across the load bed to form a row of bales and the operation of the mechanism for pushingly advancing a row of bales rearwardly on the load bed is automatically, sequentially controlled in coordination with the operation of the mechanism for picking up bales in the field and elevating them onto the load bed. The control linkage includes a p2' r of pivotally connected links pivotally interconnecting the frame of the bale wagon, the control frame 'or the hydraulically powered cross conveyor and the pusher advance mechanism, and a delay valve for coordinating the operation of the cross conveyor relative to the bale pickup mechanism, one of the links having a free end movable within a fixed path. An over-center linkage interconnecting the cross conveyor and the pusher advance mechanism controls the movement of the free end of the one link and, thereby, the positioning of the control valve between a cross conveyor mode and a pusher mode. Movement for the pair of links to position the hydraulic control valves is provided via a connectirlg link transferring motion thereto from the bale pickup mechanism.
