摘要：
A feed system of a mining combine includes a track made up of pivotally interconnected tubular segments on which is installed the combine being moved. The combine has a drive gearwheel meshing with a traction rack. The traction rack is formed by individual pivotally interconnected segments comprising side members interconnected by pins engageable with the drive gearwheel. According to the invention, the traction rack is connected to the track for rotation thereabout by means of pivotal joints which are provided at points of the joints between the segments of the track. Positive engagement of the traction rack with the drive gearwheel is maintained.
