ABSTRACT:
The tracked undercarriage for harvesters has a wheel-track drive unit (3) disposed on both sides of the machine, and each drive unit (3) has two rockers (5, 6), height-adjustably seated on a common, horizontal axle (4) extending transversely in respect to the direction of travel, two dual wheels (7, 8), rotatably seated on the free ends of the two rockers (5, 6) and an endlessly revolving track (9) guided around both dual wheels (7, 8), one tensioning element (28) for the track (9) acting on at least one dual wheel bearing (20) and a drive for at least one dual wheel (8). A separating line (TL) is drawn outside of the axle (4) in one rocker (6), wherein a releasable connection (16, 17, 18) with the other rocker (5) extended past the axle (4) is located in this separation line (TL), and this removable rocker (6) is embodied as a transmission housing (11) with a cardan shaft inlet (12) and toothed-wheel gear (13, 14, 15) for driving the dual wheel (8) seated on the removable rocker (6).
