The TN 55 D (DT) is powered by a three-cylinder diesel engine of 2.9 litres, delivering 36.8 kW at 2,300 rpm, roughly 50 hp, with 185 Nm of torque. On manufacturers with Italian roots, the DT suffix stands for doppia trazione, meaning four-wheel drive; at an unladen weight of 3,010 kg and a wheelbase of 2,130 mm, the machine has a design top speed of 30 km/h.
Compact four-wheel-drive tractors of this power class suit grassland work, transport and implements driven off the power take-off at the standard speeds of 540 or 1,000 rpm. The combination of four-wheel drive and a relatively low unladen weight makes it easier to work on waterlogged grassland without compacting the soil excessively. The lower top speed of 30 km/h places the tractor, under German rules, in driving licence category L.
When buying a used four-wheel-drive compact tractor of this age, check the front axle transfer gearbox and freewheel hubs, since four-wheel-drive components wear unevenly under uneven use. The power-take-off clutch, the tightness of hydraulic couplings and cracks in the axle boots, which are usually the first parts to fail on four-wheel-drive tractors, are equally worth checking.

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.
