Oliver three-digit series (1958–1964) – 440 to 995 from Charles City: the hundreds number as size class, 990 GM and 995 Lugmatic with GM two-stroke diesel, petrol, LPG and diesel
The three-digit series was Oliver's programme of 1958 to 1964, the transition from the Super models of the 1950s to the four-digit ranges – and the period in which White Motor took over the maker from Charles City, Iowa, in 1960. The type logic: the hundreds number orders the size class in ascending order – 440 the small row-crop tractor (successor to the Super 44), 550 about 40 hp, 660 about 50, 770 about 55, 880 about 65, 950 about 80 hp – and the 990 GM and 995 Lugmatic are the big models with the 3-71 two-stroke diesel from General Motors (Detroit Diesel), which Oliver offered as an alternative to its own engines; Lugmatic denotes the version with torque-converter transmission. The own engines are three-, four- and six-cylinders of 2.3 to 4.9 litres, most available as petrol, LPG or diesel, at rated speeds of 1,750 to 2,000 rpm.

The register lists 8 versions with 19.9 to 63.7 kW from engines of 2,288 to 4,942 cm³, unladen weights from 1,268 to 5,101 kg, lengths from 3,045 to 3,657 mm, widths from 1,695 to 2,055 mm and heights from 1,861 to 2,286 mm.
The series brought Oliver's hallmark of those years – the six-cylinder smoothness argument of the 770 and 880 against the competitors' four-cylinders – and the GM models are among the loudest and most sought-after collector tractors of North America.
On used tractors, originality, engine condition and carburettor or injection, blower and injectors on the GM two-stroke, clutch, gearbox and hydraulics, sheet metal and tyres count; parts run through Oliver collector dealers.

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.
