ABSTRACT:
A bale handling implement is disclosed having a pair of elongated arm members rotatably attached to a mounting support such that the arms are rotatable about their longitudinal axes. The arms, which have several teeth extending from one side, rotatably pass through a support bushing that is directly attached to the mounting support. The elongated arms are rotated by a single, fluid actuated power cylinder attached to the mounting support between a position in which the teeth extend generally downwardly and a position in which the teeth engage the hay bale to facilitate its lifting. A linkage mechanism interconnects the actuating rod of the fluid actuated power cylinder to crank arms attached to the elongated arm members such that extension and retraction of the actuating rod causes the arm members to rotate about their longitudinal axes.
