Oliver 99
Built: 1953–1954 · Series: FLEETLINE-SERIE
More machines from model year 1953
Oliver Fleetline series: the post-war 66 to 99 range from 1948 to 1954, 18.4 to 47.8 kW from four- to six-cylinder engines of 2,118 to 4,942cc, optional petrol, kerosene, LPG or diesel operation
The Fleetline series replaced Oliver's pre-war 70/80/90 range in 1948 and ran until 1954 with four base models: the 66, 77, 88 and 99; the HC and KD suffixes denote different versions within the 77 and 88 series. The engines came from Oliver's collaboration with Waukesha and, depending on the model, were set up for petrol, kerosene, LPG or diesel, letting post-war American farms choose whichever fuel was cheapest to hand.

The register lists 4 versions with 18.4 to 47.8 kW from four- to six-cylinder engines of 2,118 to 4,942cc, kerb weights from 1,315 to 3,758 kg, lengths from 3,146 to 3,604 mm, widths from 1,583 to 1,727 mm, heights from 1,373 to 1,753 mm and rated speeds from 1,600 to 1,675 rpm.
The Fleetline series marked Oliver's move into modern post-war farm machinery with streamlined bodywork, an enclosed radiator grille and the six-cylinder engines in the larger models that became characteristic of the brand; it competed with the John Deere Model A/B, Farmall H/M and Massey-Harris 44.
When buying used, check the carburettor or fuel system according to fuel type, engine oil-tightness, clutch and gearbox condition, and corrosion on the mudguards and body panels; spare parts for the widely produced Fleetline series are comparatively easy to find through the North American vintage tractor market.

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.
