This book comprehensively documents the activities of International Harvester Company (IHC) and its influence in Australia and New Zealand, from its inception to its merger with Case as Case IH. IHC began with a merger of harvesting machinery companies to form the International Trust, the world's biggest farm machinery enterprise at the time. Then IHC became involved with tractors to become the world's largest tractor and full-line machinery maker, setting production records that stand to this day. The book offers details on tractors and machinery models for collectors of the International Harvester brand line up. It also provides information and anecdotes about enthusiasts who collect, restore, and maintain vintage machines. International Harvester is copiously illustrated with much previously unpublished material.
