Oliver Super series (1954–1958) – the Fleetline successors from Charles City: Super 44 to Super 99, the number as size class, GM for the Detroit two-stroke diesel, D for diesel
The Super series was Oliver's programme of the mid-1950s – the upgrade of the Fleetline models 66, 77 and 88 of 1948, with which the maker from Charles City, Iowa, had faced the post-war years, for more power, hydraulics and the new three-point linkage. The type logic: Super marks the generation, the number orders the size in ascending order – Super 44 the small three-cylinder row-crop tractor, Super 55 the utility tractor of about 34 hp, Super 66 and Super 77 the mid-range, Super 88 the big six-cylinder of about 60 hp, Super 99 the top model – D the diesel, and GM on the Super 99 the General Motors 3-71 two-stroke diesel with which Oliver offered the most powerful tractor of its time. The own engines are three-, four- and six-cylinders of 2.3 to 4.9 litres at low rated speeds of 1,600 to 2,000 rpm, available as petrol or diesel – Oliver's six-cylinders were regarded as the smoothest of the class.

The register lists 7 versions with 18.6 to 58.7 kW from engines of 2,288 to 4,942 cm³, torque from 329 to 652 Nm, unladen weights from 1,089 to 3,611 kg, lengths from 3,048 to 3,657 mm, widths from 1,695 to 2,038 mm and heights from 1,803 to 2,286 mm.
The Super series is the most-collected Oliver generation after the 50 series; the Super 99 GM with its two-stroke sound is regarded as the loudest tractor of the American collector scene, the Super 55 as one of the first American utility tractors with three-point linkage.
On used tractors, originality, engine condition and carburettor or injection, blower and injectors on the GM, clutch, gearbox and hydraulics, sheet metal and tyres count; parts run through Oliver collector dealers in North America.

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.
