Abstract: A hay harvesting machine comprises a movable support; a drum supported on the support for rotation about a horizontal axis transversal to the direction of motion of the machine; driving means for rotating the drum; conveying members for the cut mass provided on the periphery of said drum; and a plurality of rollers each supported on said chassis for freewheeling about an axis parallel to the axis of rotation of the drum, said rollers being arranged concentrically about the periphery of the drum and being closely spaced peripherally from each other and from the drum, whereby the cut mass is moved by said conveyor means upon rotation of the drum into the space between the rollers and the drum where it is broken up before being discharged to the ground.

Abstract: A spout of an agricultural ejector is mounted on the ejector housing for angular displacement about an axis. An planetary gear transmission is interposed between the spout and the housing and has one bevel gear stationarily connected to the housing and another bevel gear connected to the spout for rotation therewith. A bevel pinion is mounted on a sleeve for rotation about its own axis and for orbiting about the axis of the spout in meshing engagement with the bevel gears. A cylinder and piston unit is pivotably connected to the housing and to the sleeve and rotates the sleeve so that the planetary gear transmission causes the spout to rotate at twice the angular speed of the sleeve. In this manner, the direction in which the spout ejects can be rapidly changed.

Abstract: An agricultural machine for picking up and chopping stalks and like materials has an intake unit for materials to be chopped which includes a first housing and a material pick-up device, a chopping unit for chopping the picked-up material which includes a second housing and a chopping device mounted therein, and a quick-release coupling arrangement which connects the housings with one another.
