An improved clamp arm and bracket design for a hay handler and unroller apparatus which accommodates a wide range of varying lengths of hay bales is disclosed. The improved clamp arm includes an improved bracket design which is connected to a frame which in turn is connected to a tractor via a three point hitch. Each bracket can be mounted to the frame in one of two possible positions where the bracket is rotated 180 DEG from a first position where the bracket extends inwardly to obtain a second position where the brackets extend outwardly. These alternate positions enable the apparatus to provide for varying distances between said clamp arms by allowing for three possible arrangements of the brackets, namely, both brackets in the first position to accommodate shorter bales, both brackets in the second position to accommodate longer bales, and one bracket in the first position and the other bracket in the second position to accommodate bales of an intermediate length.
