The T-670 double-axle agricultural trailers are designed for transporting agricultural produce. Sideboards and backside with centrally controlled opening/closing system ensure quick unloading. An adjustable gate in the backside makes it possible to control the flow of loose materials. The trailers are characterised by high leak-proofness, which enables the transport of loose materials, e.g. rape, etc. The trailers are provided with the rear hitch and couplings for attaching the second trailer. The trailers are fully adapted to use on public roads with the speed of 40 km/h. They are characterised by solid design, which guarantees failure-free operation for years.
