<p>A grain harvester with a frontal device, which is mounted in such a manner as to allow turning around the axis, a transversal driving axis, made in such a manner as to allow extending the range of turns of the frontal device while harvesting yield on a slope excluding a hazard of support of the mass harvested in the entry part of an inclined conveyer. The frontal device is mounted on a rotary frame, capable of rotating additionally also relative to the frontal device, in such a manner that above all the rotary frame is mounted in such a manner as to allow turning around the axis and, additionally to this, for increasing the rotational displacement of the frontal device - in such a manner as to allow rotating around the similar axis. The invention is especially usable for a grain harvester, in which at least running wheels, mounted on the driven axis, can be mounted at different height in relation to the body of the combine, for instance while the combine is working on a slope.</p> |
