The Massey Ferguson 35X, launched in late 1962, represented the pinnacle of small tractor engineering with its impressive 39.6 horsepower output. The "X" in its name stood for "extra," signifying the additional power delivered by its upgraded Perkins A3.152X three-cylinder diesel engine.

The Massey Ferguson 168, built from 1972 to 1976, stands today as one of the rarest and most sought-after tractors from Massey Ferguson's golden era. Producing 69 horsepower from its 3.9-liter, four-cylinder Perkins diesel engine, the 168 was positioned as a significant improvement over the 165 model.

The Ford 5000, produced from 1964 to 1975, became one of the most beloved tractors in British and Irish farming history, delivering between 69 and 75 horsepower through its robust four-cylinder diesel engine. This blue and white beauty emerged as part of Ford's ambitious "Worldwide Tractor" program.
