Abstract
A harvester and a method for harvesting a crop is disclosed. The harvester includes two track drives positioned on opposite ends of a front axle of the harvester, each of the track drives including two main wheels that are arranged successively in the driving direction of the harvester, at least one auxiliary wheel positioned between the main wheels, and at least one track that surrounds the main wheels. The auxiliary wheel can interact with a bottom section of the track so that the forces to be deflected via the particular track drive into ground can be deflected at least proportionately using the auxiliary wheel. To reduce the shearing forces into the ground when the harvester turns, a control unit, depending on the steering angle of the harvester, controls a lifting unit to lift a front main wheel of a particular track drive from its home position to a lifted position.
