A tracked drive assembly for a work machine comprises a crawler frame, a crawler track, a drive wheel and a guide wheel, and an arrangement of running wheels coupled to the crawler frame, wherein the tracked drive assembly has a sensor system comprising a sensor for each of the outer running wheels
A tracked drive assembly for a work machine comprises a crawler frame, a crawler track, a drive wheel and a guide wheel, and an arrangement of running wheels coupled to the crawler frame, wherein the tracked drive assembly has a sensor system comprising a sensor for each of the outer running wheels of the running wheel arrangement, which are positioned or located adjacent to the drive wheel and the guide wheel, and at least one other running wheel which is arranged between the outer running wheels, wherein the force introduced into the crawler track via the respective running wheel can be determined by way of the sensor. A method for determining the ground pressure distribution below a work machine includes exposing the sensor to a compressive load at a running wheel.
