Massey Ferguson's Thinking Tractors Part One - Dawn of the Electronic Revolution deals with MF's early electronic controls on the 4000 series of 1979, improved in the early 1980s with the 3500 series.

Using a wealth of previously unseen archive footage, it show how the very first prototypes were tested and developed to produce the world's first 'thinking tractors' and how these were then launched to the farming public alongside the smaller 300 series machines.
