JT-Trailer Trailers up to 750 kg (Class O1)

The register lists here 175 versions with unladen weights from 120 to 730 kg at a constant gross weight of 750 kg. Widths run from 1,600 to 2,260 mm, and the lengths of most models from 3,000 to around 6,000 mm.

Class O1 trailers can be towed in most European countries without a separate trailer driving-licence category and generally without their own brake system, as long as the gross weight does not exceed 750 kg; the JT-Trailer programme thus covers the classic Finnish market for boat, motorcycle and small-load trailers, where the loading area is chosen by metre measurement rather than by model name.

On a used trailer, buyers should check the condition of the drawbar and ball coupling, corrosion on the frame and floor panel, the condition of the side boards and, on the teli versions with a tandem axle, even wear on both axles and the function of the equalising suspension. Tyre condition and the working of the lights should be checked before driving; spare parts for this weight class are generally available as standard items through the Finnish trailer trade.
