A bale accumulator is utilized to deposit bales in groups in a field. The bale accumulator includes a chute along which bales move to an upper end portion of an accumulator ramp assembly. The accumulator ramp assembly slopes downward away from the chute. The chute may rotate the bales through a quarter turn. The accumulator ramp assembly includes a plurality of guides which form compartments in which bales are accumulated. A plurality of diverter gates are operable to direct bales into each of the compartments as the bales slide along an upper side of the ramp. An exit gate is operable to an open condition to enable bales accumulated in the compartments to move along an upper side of the exit gate and be deposited in a group in the field.
