The 50er series from Oliver / Fiat includes the 1450 (4 WD). Production: 1967–1969. The engine delivers 66 hp (48.6 kW), has 4 cylinders, with a displacement of 4,397 cm³. Torque is 272 Nm. Rated speed is 1,900 rpm. The machine is 3,452 mm long, 1,480 mm wide and 1,476 mm high. The unladen weight is 2,720 kg. The wheelbase measures 2,169 mm. Ground clearance is 465 mm. Top speed is 23 km/h. Transmission: 7 V/2 R or 14 V/4 R. The engine is water-cooled. Tyres: front 6.50-18 ASF (4 WD: 9.5-24 AS), rear 14.9-30 AS (4 WD: 18.4-26 AS). The fuel is diesel. The bore measures 108 mm. The stroke is 120 mm. The compression ratio is 15:1. Maximum torque is reached at 1,250 rpm. Construction: unit construction with subframe. The 50 er-Baureihe series covers 3 models. Rated output within it ranges from 42 to 66 hp; the 1450 (4 WD) sits at the top of that range with 66 hp. Its immediate neighbours are the 1250-A (4 WD) below it with 42 hp. Unladen weight within it ranges from 1,490 to 2,720 kg; here the 1450 (4 WD) sits at the top of that range with 2,720 kg. 7 Oliver / Fiat models across 3 series are on record.

Oliver/Fiat 50 series – US tractors 1250 and 1450 built under Fiat licence, 31 to 49 kW, three- and four-cylinder engines of 2,270 to 4,397 cm³, diesel or dual-fuel diesel/petrol

The 50 series grew out of the cooperation between the US maker Oliver and Fiat, which supplied Oliver with licence-built tractors from the 1960s; the types covered here, 1250, 1250-A and 1450, all carry the 4 WD suffix for four-wheel drive. The four-digit type numbers order the models by size, with the 1450 the largest of the three versions.

The register lists here 3 versions with 30.9 to 48.6 kW from three- and four-cylinder engines of 2,270 to 4,397 cm³, unladen weights from 1,490 to 2,720 kg, lengths from 2,997 to 3,452 mm, widths from 1,283 to 1,585 mm and heights from 1,300 to 2,355 mm, at speeds of 1,900 to 2,500 rpm.

With four-wheel drive on all three models, the range targeted more demanding terrain in North America and Europe; the combination of Oliver distribution and Fiat engineering was part of the growing international ties among tractor makers of the period, before Oliver was absorbed into the White Motor Corporation in the 1970s.

On a used example of this range, the condition of the four-wheel-drive clutch and front-axle gearing, rust on the chassis and wings, the function of the hydraulics, and, on the rare dual-fuel diesel/petrol versions, the condition of the carburettor or ignition system all count; parts for the Fiat engineering are easier to source than Oliver-specific fittings.

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.
