An innovative flop: Remembering the Ford 6000 tractor

How the cutting-edge tractor and its failure-prone transmission became a marketing nightmare for the brand

The tractors were available with either a 223-cubic inch gasoline or a 242-cubic inch diesel engine — but a groundbreaking innovation for its time, the Select-O-Speed powershift transmission behind those engines, turned out to be the tractors’ early downfall.
