Means for adjusting the sideboard

Abstract

A bale wagon has improved actuating means for adjustably moving sideboard structures supported along opposite sides of a load bed on the bale wagon in order to change the spacing between the structures so that formation of stacks having different widths may be accommodated on the load bed. Each of the sideboard structures is supported by an upstanding member. The improved means includes an elongated tube extending along and rotatably mounted to each upstanding member and a set of upper and lower linkages associated with each elongated tube, the linkages respectively interconnecting upper and lower portions of the elongated tube with respective adjacent end portions of upper and lower means which support upper and lower portions of the respective upstanding member for movement toward and away from the load bed side. Furthermore, each set of the linkages are retractible and extensible upon respective rotation and counter-rotation of the elongated tube. Therefore, by selectively rotating and counter-rotating the elongated tube, the linkages may be retracted and extended and thereby cause selected movement of the respective one of the upstanding member and the one of the sideboard structures supported thereby toward and away from the corresponding load bed side.
