摘要：
The invention relates to a machine combination including a rotary harrow (1) and a seeding machine (2), the weight of the seeding machine (2) bearing on the roller (7) of the rotary harrow during operation, which roller (7) via arms (8) orientated in the direction of travel (A) is connected, pivotably about pivot shafts (9) which are disposed horizontally and transversely relative to the direction of travel, with a frame portion of the rotary harrow (1), which seeding machine (2), via a construction which, in side view, is a quadrangle hinge construction (3) by means of pivot shafts which are also disposed horizontally and transversely, is coupled with the trestle (10) of the rotary harrow, the downward freedom of movement of such quadrangle hinge construction (3) being limited by means of a flexible limiting element (4), disposed between the trestle (10) and the quadrangle hinge construction (3). The roller (7) and the seeding machine (2) are interconnected by means of a slotted hole construction (55 - 69), while the slotted hole (59, 60) is orientated substantially horizontally and in the direction of travel (A) and is included in one of the two machines (1, 2) and a supporting element (51) which extends substantially transversely to the direction of travel (A) and which, movable in the slotted hole (59, 60), is included in the other machine. <IMAGE>
