摘要

Method and device for harvesting grasses, such as e.g. in the form of “springs” and “plugs”, in which across the ground and at some distance over it, a shaft (2) is moved transversely to its longitudinal direction and is rotated simultaneously. The shaft is provided with mutually spaced supporting plates (7) for receiving milling cutters (8) across its length, said cutters extending almost in parallel to the shaft (2). The shaft (2) is supported by a frame (1) to be coupled to a tractor, in which means (13-19) have been provided for adjusting the shaft at the desired height above the ground. The milling cutters (8) of successive supporting plates (7) can overlap at least partly. The supporting plates (7) can also be provided with aerating knives (24), which can be fixed in a certain position. Further, a discharge conveyor or car and sieving facilities can be provided.
