Abstract
A bale carrying device comprised of a cross bar frame structure having a pair of spaced apart rearwardly extending arms pivotally mounted on the ends of the cross bar frame structure for pivotal movement about the vertical axis of the cross bar; and having means for laterally adjusting the pivotal axis of the arms for selectively varying the width of the space between the arms in order to accommodate large round bales of varying thicknesses.

- a cross-bar frame structure with a plurality of horizontally spaced apart vertical apertures,
- securing means on said frame to secure said frame to an implement hitch of a prime mover,
- a pair of spaced apart rearwardly extending arms pivotally mounted by hinge means on said cross bar frame structure for pivotal movement about a vertical axis,
- said hinge means comprising a pin for pivotally mounting each of said arms to said cross bar, said pin being received within one of said apertures in said cross bar frame and being selectively movable to other of said apertures,
- a hydraulic cylinder having an extendable and retractable ram at one end and mounted at its opposite end to one of said arms, said ram being operatively secured to said other arm for selectively effecting the pivoting of said arms towards and away from one another, and
