rear driving wheels on the ground, the front steering wheels had improved contact with the ground. Consequently, the "rearing and bucking" of overloaded tractors was reduced, making tractors much safer for the operator. Ferguson design implements Other innovations Ferguson's designs, for tractors, were the first with single-wheel brakes that allowed the driver to turn sharply by braking the inside wheel. The TE20 was one of the first tractors to have a four-speed gearbox, with integrated differential, and a hydraulic system. Merger with Massey-Harris In 1953 Ferguson and Massey-Harris merged, and the combined company Massey-Harris-Ferguson (later shortened to Massey Ferguson) became the manufacturer of the tractors and other designs. By then, many manufacturers had developed their own three-point linkages, and the linkage had become standardised worldwide.
