Abstract: A loading device for the loading and ultimate transport of rolled bales. The unit is particularly designed for the loading of rolled bales onto a trailer unit such that the same may be transported from one location to another location. The bale loader is used for picking rolled bales from the ground, arranging them onto a transport trailer, moving the same upon the trailer to fully load the trailer and thereafter, after the destination is reached, deliver the bales from the trailer. The loading device includes a hydraulically aperated pivoting arm which will pick up individual bales and deposit and locate them so as to form pairs of bales in side-by-side relation upon a lower run of the trailer and deposit a third bale intermediately arranged upon the two lower bales such that three bales are arranged in a stacked relation upon the trailer.
