The Oliver 2055 and 2155, introduced in 1971, were just Minneapolis-Moline tractors painted green, but they were already replaced the following year by the Oliver 2255, equipped with a Caterpillar V8 engine, which was, except for the engine, almost the same tractor as the earlier 2050 and 2150. Only the front part of the frame construction had to be widened. The transmission was still an unsynchronized 6+2. However, almost all tractors were equipped with an optional 3-speed hydraulic power shuttle. The same drivetrain continued even after the Olivers in the White range. The power take-off (PTO) was standard at 1000 rpm, with an optional 540 rpm available via a reversible shaft. The closed hydraulic system had a 75-liter pump but a rather modest lifting capacity of 2700 kilograms. The four-wheel-drive model had a mechanical Clark front drive and a notably short wheelbase. The cab was spacious, had a flat floor, and featured suspended pedals, but it was not quite as refined as the best competitors in the early 1970s.

In Canada, the 2255 was sold in red Cockshutt colors, but now under the White brand.

In 1974, the engine was replaced with a newer 10.4-liter model while maintaining the same power output.
