The FLEETLINE series from Oliver includes the 88 HC/KD. Production: 1947–1954. The engine delivers 41.5 hp (30.5 kW), has 6 cylinders, with a displacement of 3,784 cm³. Rated speed is 1,600 rpm. The machine is 3,604 mm long, 1,727 mm wide and 1,753 mm high. The unladen weight is 2,173 kg. The wheelbase measures 2,007 mm. Top speed is 20 km/h. Transmission: 6 V/2 R or 4 V/4 R. The engine is water-cooled. Tyres: front 6.00 x 16 (RC = 9.00 x 10), rear 13 x 26 (RC = 12 x 38). The fuel is Benzin/Kerosin/LPG/Diesel. The bore measures 88.9 mm. The stroke is 101.6 mm. The compression ratio is 6.75:1. Construction: frame construction. Around 7.966 (RC = 23.232) units were built. The FLEETLINE-SERIE series covers 4 models. Rated output within it ranges from 25 to 65 hp; the 88 HC/KD sits in the middle of that range with 41.5 hp. Its immediate neighbours are the 77 HC/KD below it with 36 hp and the 99 above it with 65 hp. Unladen weight within it ranges from 1,315 to 3,758 kg; here the 88 HC/KD sits in the lower part of that range with 2,173 kg. 70 Oliver models across 13 series are on record.

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.
