ABSTRACT:
A rotary snow plough includes a ploughing drum, a running gear and a motor drive. A holding-down member is connected to the running gear and is arranged in front of the ploughing drum. The holding-down member includes upwardly directed holding-back surfaces. During operation, the rotating ploughing drum creates an upward reaction force, and snow lying above the holding-down surface creates an opposing downward reaction force. The effect developed by the holding-back surfaces is greater, the greater the upwardly directed reaction force, which arises from the quantity and quality of the snow.
