Introduced in 1977, these harvesters marked a departure from traditional combine harvester design, in that threshing and separation was performed mainly by a rotor, as opposed to the drum and straw walker type models used previously. This is shown in the image at right, where the bulk of the processing area is devoted to a cylinder, that spins and threshes grain from the grain heads and allows for far greater capacity than the previous drum and walker design of harvester. This increase in capacity has led to a significant productivity increase of harvesters and therefore farmers who use them. The 16 series In 1985, International Harvester and Case Corporation merged. The 16 series was the first harvester series released by the new Case International and was an upgrade to the 14 series rather than a replacement. All models of the 14 series had 16 series equivalents, in the 1620, 1640, 1660, 1670, 1680 and 1682. The rotary design by International Harvester was the first of its kind to be mass-produced and its patent over the design gave IH a competitive advantage over its rivals, including John Deere, Massey Ferguson, New Holland and others.
