The David Brown 950 Implematic was introduced in September 1959 to upgrade the David Brown 950. The tractor had a Red colour scheme with powder cream wheel centres and grills. A range of engine options for all fuels was offered. The model was upgraded to the David Brown 950 Implematic (A&B version) in December 1960.
