Oliver 55 series (1969–1975) – 1555 to 2655 from Charles City: the last Olivers before White, Minneapolis-Moline kinship, the Fiat-built 1265, 4 WD and the 2255 with V8, 33 to 109 kW
The 55 series was the last tractor programme to carry the Oliver name: the company from Charles City, Iowa, had belonged since 1960 to the White Motor group, which bought Minneapolis-Moline and Cockshutt in 1963, and in 1975 the three traditional brands disappeared into White Farm Equipment. The 55s replaced the 50s in 1969 and order size by the first digits in ascending order: 1555 and 1655 the mid-range, 1755 to 1955 the six-cylinder large tractors, 2055 to 2655 the heavy models, which were technically Minneapolis-Moline designs in Oliver sheet metal – the 2255 carried a V8 and the 2655 the eight-cylinder of 9,583 cm³ as a four-wheel-drive tractor. The 1265 came from Fiat in Italy, the 1555 to 1955 optionally with petrol, diesel or LPG; 4 WD marks four-wheel drive.

The register lists 11 versions with 33.1 to 108.9 kW (45 to 143 hp), 2,592 to 9,583 cm³ with three to eight cylinders, unladen weights from 1,870 to 9,004 kg, lengths from 2,921 to 5,944 mm, widths from 1,597 to 2,438 mm and heights from 1,489 to 2,515 mm.
Oliver stood for green tractors with a six-cylinder reputation – the Waukesha and Oliver's own in-line engines were regarded as smooth – and the 55s were the range in which the mixing with Minneapolis-Moline and Fiat foreshadowed the brand's end.
Used Olivers are sought-after collector tractors in the USA with an active club scene; when buying, originality, engine condition, the Hydra-Power transmission with powershift step, hydraulics and the availability of sheet-metal parts through remanufacturers are what count.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
