An agricultural rock collection and rock rowing machine and method is disclosed for collecting rocks in fields and then for dumping these rocks in a row for easier pickup or for storage. The machine includes one or more rock collectors for receiving rocks along with soil, smaller rocks and field debris that may accompany the rocks, and for screening out soil, field debris and smaller rocks that are small enough to pass through gaps between the grates of the rock collectors. The machine also includes rock lifter plates that assist the lifting of rocks from the field up onto the rock collectors for screening and collection. A further embodiment of the machine includes a rock collector unloader mechanism for raising the rock collectors thereby unloading the collected rocks roughly in rows. These rows may be formed off the field, or picked up more easily by hand or with a conventional row-collecting rock picker, and then removed from the field. The rock collector unloader mechanism may be attached to a trailer frame portion of the machine, the trailer frame serving to pull the rock collectors when the trailer frame is attached to a tractor or suitable pulling machine.
