White Motor Corporation of Cleveland, Ohio had a long history of truck manufacturing. On November 1, 1960, White Motor acquired Oliver, changedhe name to Oliver Corporation, and made it a wholly owned, separately operating subsidiary of the White Motor Corporation.[19] White also acquired Cockshutt Farm Equipment of Canada in February, 1962, and it was made a subsidiary of Oliver Corporation. Cockshutt had also previously in 1928, marketed tractors made by Hart-Parr and again from 1934 through the late 1940s, marketed tractors made by Oliver, only changing the paint color to red, and changing the name tags to Cockshutt. Minneapolis-Moline became a wholly owned subsidiary of White Motor Corporation in 1963. The Minneapolis-Moline line was blended into that of Oliver until there was virtually no difference between them. In 1960, the new four-digit tractor models appeared. Among them were the 1600, 1800 and 1900 models. In 1969 White Motor Corporation formed White Farm Equipment Company, almost immediately after a transitional period when virtually identical tractors were marketed under different trade names. A few models were sold as Oliver, Minneapolis, or Cockshutt, the major difference being the paint colour. As the transaction continued, the White name was more and more applied to the tractor line, with the Oliver 2255, also known as the White 2255, being the last purely "Oliver" tractor. With the introduction of the White 4-150 Field Boss in 1974, the White name would be used, henceforth to the exclusion of all others. White Motor Corporation shut down the original Oliver Chilled Plow Works factory (factory no. 1) in 1985. The Oliver buildings remained vacant until 2002 when most were demolished to make way for an industrial park. The Oliver powerhouse is now restored and occupied by Rose Brick & Material Rose Brick & Material
