County Super-4/6

County, which manufactured Fordson-based crawler tractors, conducted a few wheeled tractor experiments in the 1950s. The first was the 1954 Four-Drive, a crawler tractor equipped with wheels. Usage applications were hard to find, except for the sugarcane plantations in Puerto Rico. The County Hi-Drive was a raised version of the Fordson Major, also targeted at sugar growers. The Highway Dexta was a road version of the Dexta compliant with British traffic regulations. In addition, County fitted half-track conversions to Dextas and Majors.

In 1961, County introduced the Super-4. This tractor, based on the Fordson Super Major, had four equally sized wheels. Power was transmitted to the front axle separately via shafts on each side of the frame. Due to this solution, the Super Major’s differential lock now affected all wheels. A downside was the large turning radius.

The front axle utilized many standard components from Fordson and the Ford Thames Trader. The engine was the standard 52-horsepower Super Major unit, and the transmission was 6+2. The wheelbase was 180 cm, over 20 cm shorter than the Major.

In 1962, the more powerful 95-horsepower Super-6 was introduced, to which County had fitted Ford's 5.4-liter 590E industrial engine. The engine hood was completely redesigned for this model.
