CRAWLER DRIVE FOR AN AGRICULTURAL WORK MACHINE AND AGRICULTURAL WORK MACHINE

A crawler drive for an agricultural work machine is disclosed. The crawler device includes front and rear main wheels, front and rear main frames associated with the front and rear main wheels respectively, two support wheels, a running belt surrounding the main wheels and an articulation point to pivotably connect to a body of the agricultural work machine while forming a machine axis. The two main frames, coupled to one another, pivot about a common pivot axis. The support wheels are positioned on a common support frame, which is pivotably connected to the front main frame. A coupling member is coupled at a swing arm end of the coupling member to the support wheel swing arm and at a frame end of the coupling member to the rear main frame and thereby couples the support wheel swing arm and the rear main frame to one another.
