Ursus 2812 to 5714 – the Massey Ferguson licence tractors from Warsaw (licence agreement 1974): the last digit 2 for rear-wheel, 4 for four-wheel drive, Perkins engines built under Ursus licence of 2.5 to 4.1 litres
The Ursus models 2812 to 5714 are Polish Massey Fergusons: in 1974 the Warsaw maker Ursus concluded a licence agreement with Massey Ferguson and Perkins for the tractors MF 235 to MF 290 and their Perkins engines, to supply the Polish market and exports to the Comecon area with a modern mid-range – alongside its own Ursus C-360 and C-385, which were based on Zetor licences. The type logic: the first digits order the size in ascending order – 2812 the smallest class at about 38 hp, 3512 about 47 hp, 4512 about 55 hp, 5714 about 81 hp – the last digit distinguishes 2 for rear-wheel drive and 4 for four-wheel drive (3514, 4514, 5314, 5714). The engines are Perkins designs of Ursus manufacture: the three-cylinder AD3.152 of 2.5 litres in the small, the four-cylinders of up to 4.1 litres in the big models.

The register lists 8 versions with 27.9 to 58.1 kW from three- and four-cylinders of 2,502 to 4,068 cm³ at 2,000 to 2,200 rpm, torque from 155 to 267 Nm, unladen weights from 2,170 to 3,500 kg, lengths from 3,205 to 3,820 mm, widths from 1,690 to 2,010 mm and heights from 2,240 to 2,670 mm.
The licence Ursus are still at work in Poland in large numbers today – a 3512 or 4514 is the everyday tractor on small and medium farms in Masovia and Podlasie because Perkins parts are available everywhere.
On used tractors, operating hours, the condition of the Perkins engine (compression, injection pump), clutch and gearbox, four-wheel-drive clutch on the 4 models, hydraulics and sheet metal count; parts run through the Ursus successors, Perkins and the Polish parts trade.

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.
