There are two types of chopping knife systems on potato forage chopper machine. First group of knives are used for chopping the parts of the plants such as cotton, pepper, tomato, etc. remaining in the field and to distribute it to the field ground. The second group of knives are used in chopping potato and the turnip, the plants on which the lifting machine is operated after cutting. Potato forage chopper breaks down the green body of the potatoes and the weeds in the field before harvesting the potato and distributes them homogeneously to the field surface thanks to its superior spinning ability and creates comfortable operating environment for the potato harvest. After the lifting of the potato, the potato stayed under the weeds distributed on the surface of the field a small parts is prevented. Potato forage chopper is connected to the tractor with three-point hitch system. Thanks to the rear roller, it allows the lifting machine to make a better sifting.
