Comedian Patrick Kielty is presenting a new documentary about the story of a bitter fall out between the Ford Motor Company and the Northern Ireland inventor of the modern-day tractor.

Tractor Wars, recounts the multimillion-dollar court battle involving Harry Ferguson and Ford.

In the late 1930s Ferguson, who developed the three-point linkage system now used in almost all tractors, struck a deal with Henry Ford to mass produce a new line of tractors.

However, this "gentleman’s agreement" would soon unravel in spectacular fashion, leading to a major lawsuit over an alleged patent infringement.

Kielty’s documentary is one of a series of shows unveiled by BBC Northern Ireland for its autumn schedule.
