Patent number: 7949442Abstract: A method and system for boosting a torque output of a drive train comprises an engine speed detector for detecting an engine speed of an engine having a baseline torque versus engine speed curve. A data processor determines if the detected engine speed is within a first range of engine speeds, if the detected engine speed is within the first range, the electric motor is activated to rotate substantially synchronously with the engine speed within the first range in an electric propulsion mode in accordance with a supplemental torque versus engine speed curve. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a lower engine speed point and a higher engine speed point.Type: GrantFiled: February 7, 2007Date of Patent: May 24, 2011Assignee: Deere & CompanyInventors: Alan David Sheidler, Brian Joseph Gilmore, Mark Charles DePoorter, Peter Finamore, Duane Herbert Ziegler, Joseph Albert Teijido

Patent number: 7874899Abstract: An agricultural harvester includes a support frame and a hopper coupled to the support frame. The hopper is configured to store an agricultural product during a harvesting operation. An unloading system is coupled to the support frame. The unloading system is configured to transport agricultural product received from the hopper to an off-machine location. The unloading system includes a metering gate, a transfer conveyance, at least one sensor, and an electrical processing circuit. The metering gate is positioned near a bottom of the hopper and in communication with an interior of the hopper. The transfer conveyance has an inlet end and a discharge end. The inlet end is in communication with the metering gate. The at least one sensor provides an output signal representing an operating parameter associated with an unload rate of agricultural product through the transfer conveyance during an unloading operation. The electrical processing circuit is coupled to the metering gate and the at least one sensor.Type: GrantFiled: May 18, 2009Date of Patent: January 25, 2011Assignee: Deere & CompanyInventors: Ryan Patrick Mackin, Daniel James Burke, Bruce Alan Coers, Mark Charles DePoorter

Patent number: 7801653Abstract: A method and system for boosting a torque output of a drive train comprises a torque sensor for detecting an engine torque of an engine having a baseline torque versus engine speed curve. A data processor determines if the detected engine torque is within a first torque range, if the detected engine torque is within the first range, the electric motor is activated to rotate substantially synchronously with a corresponding engine speed associated with the detected engine torque in accordance with a supplemental torque versus engine speed curve.

Patent number: 6692352Abstract: Rigid cover panels of the cover for grain storage tubes on combines, harvesting machine, are preferably fabricated of double-wall plastic to limit weight of the cover while providing desired strength and rigidity. The rigid cover panels can be pivoted about top edges of an underlying grain tank whereby the cover panels function as a height extension of the underlying tank, thus to increase the grain-carrying capacity of the tank. Flexible transition panels are preferably mounted to the rigid cover panels to bridge spaces between edge regions of the rigid cover panels when the rigid cover panels are raised to their upright, tank-extending orientations. A preferably single underlying actuator in the tank, in combination with mechanical linkages, can simultaneously raise all the rigid cover panels, all the flexible transition panels, and the discharge end of a clean grain elevator which discharges grain into the tank.Type: GrantFiled: October 24, 2001Date of Patent: February 17, 2004Assignee: Deere & CompanyInventors: Edwin Milton Gerber, Russell Andrew Huesmann, Jr., Chad Allen Dow, Mark Charles DePoorter, Garrick William Herbst, Lawrence Paul Begyn

Patent number: 6206779Abstract: A grain tank extension having side panels that are rotatably mounted to the grain tank to lower the extension by pivoting the side panels into the tank for storage. Corner panels are provided between adjacent side panels and are integrally formed with the stud at each end for coupling the corner panels to the side panels. Flanges extend beyond the ends of the side panels and overlap abutting ends of adjacent comer panels. The flanges each have an aperture that receives the stud from the adjacent corner panel. The stud is held therein by a retaining pin to avoid the need for hand tools to lower the extension for storage. The corner panels are molded of plastic as a single piece plastic body with the studs integrally formed therein.Type: GrantFiled: May 28, 1999Date of Patent: March 27, 2001Assignee: Deere & CompanyInventors: Edwin Milton Gerber, Russell Andrew Huesmann, Jr., Todd Neil Signer, Mark Charles DePoorter, Darryl Francis Cain, Bruno Dauenhauer
