A single/double-wheel hydraulic ditcher may be fitted onto the DSL, featuring a single excavating rotor and a cutting and cleaning disc. The excavated ditch is perfectly profiled, with the bed and both walls moulded by the implements. The excavated soil is only distributed on the right side of the ditch. The spreading distance is adjustable by hydraulically acting on the position of the covers of the main rotor. In case of particularly hard soil or rich in skeleton, the ditcher may be equipped with a special tungsten tool kit specifically designed for these conditions. Wearproof tool guards are available for particularly abrasive soil.
