A track drive of an agricultural production machine is disclosed. The track drive includes a driving wheel, a front deflection roller, a rear deflection roller, a continuous caterpillar track around the driving wheel and the deflection rollers, and middle rollers between the front and rear deflection roller. The track drive further includes a track frame and a swing frame. Using the swing frame, the track drive pivots about a first axis of the agricultural production machine, and the track frame pivots about a second axis of the swing frame. The second axis is at a distance from the first axis, and a spring system or damper system is positioned between the track frame and the pivot frame. The deflection rollers are positioned on the track frame with the middle rollers positioned on a common support element, which is positioned pivotably about a third axis on the track frame.

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.

A track roller unit for an agricultural working machine has at least one first guide roller and one second guide roller. The first guide roller is mounted on a first supporting arm and the second guide roller is mounted on a second supporting arm. At least one support roller is situated between the guide rollers, and a track belt wraps around the guide rollers and the at least one support roller. A hydropneumatic damping element is assigned to at least one guide roller and/or one support roller. At least one regulated restrictor device, which is assigned to a damping element, is provided and is designed in such a way that its flow resistance is adjustable during the operation of the track roller unit.

A traction wheel for a track roller unit of an agricultural working machine has at least one drive wheel for driving an elastic track belt of the track roller unit. The at least one drive wheel comprises supporting arms which extend from an axis of rotation of the drive wheel in the radial direction in the manner of spokes and a gap is formed radially on the outside, at least between two adjacent supporting arms in each case. At least one friction element is situated, in particular detachably, radially outwardly on a supporting arm for non-positive interaction with the track belt.

A crawler vehicle has a body and at least one left and one right track roller unit. The track roller units are connected to the body via a machine axis. The track roller units comprise a first and a second guide roller as well as a first and a second supporting arm on which the guide rollers are mounted. The first and the second supporting arms of each roller unit are mounted to be pivotable independently of one another about the machine axis.
