A self-propelled implement, preferably a combine or chopper, with a track belt drive shall be designed in such a way, that the wear of the track belts is reduced during shifting caused by cornering. The drive wheels and the idler pulleys of the track belt drive are equipped on both sides of the guide elements of the track belts with freely pivoting rollers, whose turning axes are perpendicular to the axles of the track drive. They are set into motion during contact with the guide elements, thus eliminating friction. |
