Ditchers featuring two excavating rotors. The excavated ditch is perfectly profiled, with the bed and both walls moulded by the implements. The excavated soil is equally distributed on both sides of the ditch. The spreading distance is adjustable by manually acting – or hydraulically if requested – on the position of the covers of each rotor. The 32° excavation angle assures the right combination between work depth and ditch opening, for good durability of the waterway over time. The width of the bed is 30 cm, for a maximum depth which may vary between 85 and 130 cm, according to the model. Typical applications of this type of ditchers are the excavation and maintenance of drainage or irrigation trenches with a permanent character.
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. Should one wish to construct complex water works with a precise direction of water drainage, Dondi offers a laser control system of excavation slope specifically developed for perfect integration on the machine.
