David Brown Legacy:
David Brown was a prominent British tractor manufacturer known for robust and reliable agricultural machinery, later acquired by Tenneco (Case IH).
David Brown Range:
The 770, 780, 880, 990, and 1200 series represent a significant part of David Brown's tractor lineup from the 1960s and 1970s, evolving from earlier designs. The 3800 and 4600 likely represent later models or rebadged Case IH models.
Manufacturing Era:
Primarily 1960s and 1970s for the core David Brown models. Later models may extend into the 1980s.
