ABSTRACT:
An agricultural machine, such as a haymaker, for the displacement of stalks, comprising a movable air-permeable screen and air displacing means arranged to induce a pressure difference across the screen thereby to cause stalks to adhere to the screen under the effect of suction. In a preferred embodiment, a blocking member is disposed to prevent the application of suction at one region of the screen to allow stalks adhering to the screen to be deposited. The air displacing means may be arranged to provide an air cushion under the machine to support the machine above the ground.
