This programme shows a wide range of big four-wheel drive tractors in action in Britain. We see some of the earliest articulated giants from both the USA and Russia at work as well as the latest flagship models from today's leading manufacturers.

Models filmed include not just the well-known names, such as the Steiger, Versatile, John Deere, Case, Massey Ferguson and Ford, but also lesser known makes like the Doe, Belarus and White.
