The invention relates to a potato harvester which can be attached to a tractor.

The requirements to be made of such facilities are firstly a good weight distribution, d. H. the correct load on the front and rear wheels. The front wheels are supposed to help achieve this a good steering have a suitable load for it, and the rear wheels must in order to achieve a good traction and a correspondingly good traction. Second, the lifting share should to be observed as closely as possible from the driver's seat, so that the driver is constantly working on the lifting share monitor and at the same time control the tractor accordingly. Third, it is desirable that the lifting coulter responds as quickly as possible to steering movements of the front wheels, thereby ensuring a good Ensure maneuverability. Furthermore, perfect cleaning of the potatoes is desirable, d. H. that a sufficient cleaning surface must be available. For any manual sorting of potatoes - desirable or sometimes necessary when consuming top quality potatoes - If possible, there should also be space for the picking staff. The center of gravity of the tractor should not be changed in a negative sense by adding the potato harvester. Another important requirement is that the potato harvester can easily be attached to normal, commercially available tractors should be cultivable.

In a known potato harvester, the lifting share and a blower wheel are on the side of the track a tractor carrying the potato harvester in the area of the receiving end of one of the three-point hitching device attached to the rear of the tractor, transversely to this running sieve chain arranged. In this known potato harvester there are also a lifting wheel and other conveying devices provided in the form of conveyor belts running transversely and longitudinally to the tractor which conveyed the crop to a collecting container arranged above the front axle of the tractor will. This potato harvester can only be attached to a specially trained tractor, because the collecting container requires a lot of space, and the tractor must be designed so that it is suitable for the Collecting container offers enough space.

In another known potato harvester that can be attached to a tractor, the lifting shares are as well in each case one transverse conveying device adjoining this and one running along a longitudinal side of the towing device Conveyor belt attached to a rigid frame connected to the tractor. From then on

the conveyor belt arranged on the longitudinal side of the tractor is the material picked up by the lifting coulter transported a wagon attached to the tractor. The attached trolley works in many cases

as disturbing, e.g. B. when driving on sloping terrain.

Another well-known potato harvester can only be attached to a tractor that has the front wheels are arranged at a close distance from each other so that they are not laterally across the width the bonnet to keep the overall width of the potato harvester within practical limits. There is also a cross conveyor belt of the potato harvester passed under the tractor's engine. So the tractor has to have a lot of ground clearance. In this known embodiment is also the cultivation of the potato harvester cumbersome and time consuming.

In a further known potato harvester, which also requires a tractor adapted to its special construction, the lifting coulter is arranged between the rear wheels of the tractor so that it can hardly be observed by the driver of the tractor. '.

Still other potato harvesters are arranged on a special vehicle or chassis, the appearance of which differs greatly from that of a normal, commercially available tractor. Here it is also known to raise the lifting coulter with the help of a hydraulic pressure cylinder.

The invention is based on the object of avoiding the disadvantages of the previously known potato harvesters and one that can be attached to a "tractor
