Abstract: Snow track preparation machine with mill installed in a revolving manner and including a pump driven by a power source, a hydraulic motor connected to the pump on the delivery side and the return side, an actuator supported on the assembly frame and realized for rotation of the mill and driving wheels. The power source is made up of a motor (2) which drives the driving wheels (5,6) and the pump (9) and actuator (16) are influenced by a control unit (17) connected to a sensor of motor rpm nD, to a sensor of the rpm of the driving wheels na1 and na2, to a sensor for the hydraulic motor of the mill and an actuator path sensor with the control unit (17) connecting the magnitudes detected by the sensors by means of an algorithm and controlling on the basis thereof the pump (9) and the actuator.
