Abstract: A self-propelled agricultural harvester. A harvester, such as a forage harvester, may comprise a machine frame, a transfer device mounted on the machine frame for transferring processed harvested material to a transport vehicle, and a hydraulic actuator connected to the transfer device. Using the hydraulic actuator, the transfer device may be rotated about a horizontal axis of rotation relative to the machine frame, and thereby a position of an end outlet of the transfer device may be changed. To reduce the vibration of the transfer device, a control and regulating device regulates vibration behavior of the transfer device to dampen vibrations of the transfer device. The control and regulating device determines a manipulated variable for controlling a proportional valve, which is operatively connected to the hydraulic actuator and is designed to adjust a volume flow of hydraulic fluid to the hydraulic actuator, for damping the vibrations of the transfer device.

Abstract: An improved vertical aeration system is provided for a grain bin having a sloped hopper bottom with a discharge opening. A pyramid frame includes legs with lower ends attachable to the hopper bottom. Concave perforated walls are attached to the legs. Braces extending between the legs provide structural support for the walls. An air duct extends upwardly and centrally into the interior of the frame, to supply air into the aeration system for flow outwardly through the perforated walls.

Abstract: A modified crescent wrench in which the adjustment and holding mechanism may be quickly engaged or disengaged. The spiral adjustment cylinder is mounted over an eccentric mandrel which is rotated about its own axis to engage or disengage the spiral cylinder with the moveable jaw of the wrench.

Abstract: A ratchet wrench of the socket drive type with a socket ejector has a control knob recessed within and reciprocable within a ratchet plug body for independently actuating both the ratchet reversing device and socket ejector.
