Abstract (en)
[origin: EP0493663A1] The rotary snow plough, which has a chassis (4) and an engine (10), has a housing (24) for the cutting drum (20). Two hold-down members designed as skids (30) are mounted on this at ground level. <??>At their front ends (40), which lie in front of the cutting drum in the direction of travel, the skids are of wedge-shaped design. When the skids penetrate into the snow during the clearing work, a downward force component arises at the skids due to the wedge shape. This counteracts the tendency of the rotary snow plough to climb up onto the snow. The hold-down members accordingly maintain contact with the ground and ensure that the snow is cleared uniformly and close to the ground. <IMAGE>
