Patent number: 10701863Abstract: A controller on a harvester vehicle is arranged to automatically identify a header in electrical communication with the vehicle upon key activation of the harvester vehicle. Programming instructions on the controller can generate notifications to the user based upon a state of activation of the float mechanism and the state of header identity detection. The controller also prompts the user to confirm the identity of the header if the detected identity of the header has changed. The controller also uses header identity to log usage hours of the header on the computer controller in association with the identity of the header such that maintenance schedules for a plurality of different headers interchangeably used on a common harvester vehicle can be tracked.Type: GrantFiled: February 23, 2018Date of Patent: July 7, 2020Assignee: MacDon Industries Ltd.Inventors: Benjamin Foster, Michael Flintoft, Sivian Loevsky, John Baldwin, Leonard Bergman

Patent number: 10701862Abstract: A harvesting header on a vehicle such as a combine harvester includes a mounting assembly comprising left and right float elements each for applying controlled left and right lift forces and arranged to allow upward floating of each end of the header in response to ground contact. Left and right sensors detect the angle of tilt of the header and a control system operates to reduce the left lift force when the left end is raised and to reduce the right lift force when the right end is raised. On a combine harvester this can be done by rotating the face plate of the feeder house in the required direction. In other systems the force generated by the left and right float elements can be directly modified. The changes to the lift force are applied only when the propulsion vehicle is tilted beyond a predetermined angle.Type: GrantFiled: February 1, 2018Date of Patent: July 7, 2020Assignee: MacDon Industries Ltd.Inventor: Ryan Patterson Thomson

Patent number: 10681865Abstract: A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.Type: GrantFiled: April 24, 2018Date of Patent: June 16, 2020Assignee: MacDon Industries LtdInventors: James Thomas Dunn, Graham Michael Leverick, Russell George Lyons, Bruce Robert Shearer, Kyle Edward Boch
