Abstract: In a reaping machine (11) having one or more rotatably drivable mowing units (12) which are provided with working implements, the mowing units (12) being held on a support frame (13) held with the tractor, the mowing units (12) are pivotally supported on the support frame (13) for easy moving adaptation of the working implements to the surface of the ground in the immediate working region by means of one or more compensating means (A2). Furthermore, the pivot axes (M) of the compensating means (A2) are arranged extending in the travelling direction and/or transversely thereof and/or inclined substantially in the vertical plane or intersect each other or the compensating means consist of a ball joint. In addition, the compensating means (A2) is configured in such a manner that at least one pivot axis (M) extending transversely of the travelling direction lies in the vicinity of the surface of the ground (10).

Abstract: An apparatus is provided for receiving, separating, distributing, and conveying mixture of materials, such as a mixture of grain, straw and chaff, in a manner that separates small particles of one kind, such as grain, from the rest of the mixture. Inner and outer co-axially aligned cylinders are mounted about a central longitudinally extending drive shaft. The inner cylinder has a generally solid wall and the outer cylinder is foraminous with a plurality of spiral guides mounted on its interior and exterior surfaces. A plurality of discs are mounted at spaced intervals along the shaft within the inner cylinder with the plane of each disc oriented at a non-right angle with respect to the axis of the shaft. A ring is mounted on the periphery of each disc and is adapted for rotation relative thereto.
