Wedge-shaped plough for the rapid and simple clearance of snow around the runway and taxiway boundary lighting at airports and airfields. Adjustable and with a special plough/brush/blower technology for front or rear attachment to the three point power-lifts of tractors or to the front lifting gear of wheel loaders. The two swivelling plough blades are equipped with plastic plates and their open, optimum inwardly curved blade shape ensures wide snow ejection.
