Abstract: An agricultural bale accumulator includes a load bed, a bale transfer module, and a bale discharge module. The load bed includes center, right and left load beds, adapted to receive and accumulate thereon first, second and third bales, respectively, from a bale chamber of an agricultural baler along a bale-receiving axis. The bale transfer module alternately transfers the bales across the load bed from the center load bed to the right load bed or the left load bed along a bale transfer axis, transverse to the bale receiving axis, responsive to a bale transfer signal to accumulate the bales on the center, right, and the left load beds in a side-by-side relationship. The bale discharge module moves between a bale accumulating position and a bale discharging position responsive to a bale discharge signal. The bale discharge module moves to the bale accumulating position to accumulate the bales on the load bed.
