    Abstract: The invention is a crop separator comprising a main platform and two angled arms and at least one attaching member with bolt holes to attach the crop separator to irrigation machinery. The angled arms, together with the outer edge of the main platform, form a smooth outer crop abutting surface such that when the crops first touch one of the angled arms, the crops are allowed to slide along the outer crop abutting surface without catching on any rough surface, ripping out the crop or otherwise damaging the crop.
