The Ulster Aviation Society is home to an iconic piece of agricultural and aviation history —  a Ferguson TEA-20 Tractor. This remarkable vehicle, with its rich history and versatile functionality, offers a unique insight into its past role within the Royal Air Force and its continued service as an aircraft tug at the UAS today.

Ferguson TEA-20 Tractor background

The Ferguson TEA-20 Tractor has a fascinating background. Developed by Harry Ferguson, a renowned engineer and inventor, this tractor gained prominence during the mid-20th century. Originally designed for agricultural purposes, the TEA-20 became an integral part of the RAF's operations, specifically as an aircraft tug.


Within the RAF, the Ferguson TEA-20 "Fergie" Tractor played a crucial role in facilitating ground operations. Its robust construction, combined with its powerful engine, allowed it to effortlessly manoeuvre aircraft around airfields, supporting various logistical activities.


From towing fighter planes to positioning bombers, this reliable petrol — yes petrol — tractor became an indispensable asset after the Second World War.

A follow-up to the iconic "Little Grey Fergie" TE20 ('TE' stood for Tractor England), the Ferguson TEA-20 was built in Coventry, England from 1948 to 1956. The main difference from its predecessor was the Standard Motor Company petrol engine it was fitted with, whereas the TE20 had a Continental engine.

It marked a major advance in tractor design, distinguished by lightweight, small size, manoeuvrability and versatility. It popularised Harry Ferguson's invention of the hydraulic, three-point hitch system around the world, and the system quickly became an international standard for tractors of all makes, remaining to this day.
