At the end of 1972, Renault tractors with less than 70 horsepower were updated. The first two digits of the model designation indicated the engine power in DIN horsepower. The engines were MWM air-cooled. The smallest model had a 2-cylinder engine, and the next ones had 3-cylinder engines. The transmission was Renault’s long-used 10+2 gear setup, with creep gears as standard. The lifting capacity remained as before at 2000 kg. Following Renault’s practice, even the smaller tractors were equipped with draft control as standard. Drum brakes were replaced by dry disc brakes. The smallest of the models, the 461, in many respects resembled the larger series. It came standard with a fully enclosed cab, which was available as an option for the smallest models. The dimensions and weights in the table are given with the cab equipped.

In 1977, models bearing the letter M were introduced, where power was added to the smaller engines. Hydraulic output and pressure were also increased. In 1980, the tractors’ color was changed to a lighter yellowish shade with black cabs. At the same time, the lifting capacity increased to 2500 kilograms.
