Abstract

Frame assemblies for a corn row head formed from components formed from different materials may include a frame portion having a first beam leg and a second beam leg formed of a first material and a skid plate attached to each of the first beam leg and the second beam leg formed from a second material different than the first material. The first material may be aluminum, and the second material may be steel. In some implementations, a breast plate joining the first beam leg and the second beam leg may be formed from the first material and may be welded to the first beam leg and the second beam leg. In other implementations, the breast plate may be formed from the second material and may be adhesively bonded to the first and second beam legs.
