The cross-country skiing course device is a combination device which, after conversion, can be used as a roller for tennis courts, tamped areas and lawn grounds. This is achieved by the unilateral insertion mounting of the drive axles as well as the roller bodies which can be filled with water ballast. Furthermore, the cross-country skiing course device has, arranged between the two rear wheels, a hydraulically liftable course shaper 20), which allows forward and backward travel on snow-free surfaces, such as e.g. in garages, on roads and across kerbstone thresholds without the course shaper 20) having to be scratched or disconnected. The chassis, which consists of a front and rear bolster V) and H), is of articulated design and has individually driven front and rear axles. Both axles can be driven simultaneously and each axle can be driven separately by oil engines. This results in 2 speed ranges. <IMAGE>
