Oliver 440-550
In the redesigned 1958 model series, the grilles were renewed and the yellow accent color was changed to white. The engines also received more power. In this respect, the 550 was updated only a year later, when its engine was bored out to a larger size. Features of the 550 included a weight transfer system, dual disc brakes, and an independent power take-off. Power steering was available as an optional extra.
The 440 arrived in 1960, when production was moved to another factory. Aside from the color scheme, its changes compared to its predecessor were minimal. The lift cylinders were larger than before. Sales of the 440 remained limited, and the model was discontinued in 1962.
In 1963, the 550 also received a cast iron grille consistent with the new larger models.
