Frost protecting straw matting for bulb fields - is removed by tractor drawn suction fan with flexible rubber seal contacting soil surface

摘要

The mobile unit removes from the land mown grass and particularly straw used in winter to cover root-crop and flower beds. The straw etc. is sucked up from the land, typically by a tractor-mounted fan with suction intake near the tractor and aimed at the soil and equipped with a rubber strip round the edge. Inside the intake there can be adjustable teeth extending outwards, to loosen the material on the soil.
