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.
