Publication number: 20180118284Abstract: A ballast assembly for a work vehicle. The ballast assembly includes a frame, a ballast weight, and a lift. The frame is included in an underside of the work vehicle. The ballast weight has a first portion and a second portion. The lift has an upper end pivotally coupled to the frame and a lower end releasably coupled to the ballast weight. The first and second portions are configured to engage with a ground surface and the frame, respectively, when the ballast weight is loaded onto the work vehicle. The first and second portions are configured to engage with the frame when the ballast weight is loaded onto the work vehicle.Type: ApplicationFiled: November 2, 2016Publication date: May 3, 2018Inventors: STEVEN A.

Patent number: 9290093Abstract: A vehicle attachment and control system for a vehicle attachment are described. The attachment includes a chassis configured to be attached to a vehicle with an onboard power source. The attachment includes an attachment power source supported by the chassis and an energy storage device supported by the chassis and configured to receive power from the attachment power source. The attachment includes a control system configured to transmit a signal to, and receive a signal from, the attachment power source and/or the energy storage device. The control system, the attachment power source, and the energy storage device are configured to provide power from the attachment power source and the energy storage device, via power transfer connections between the vehicle, or an associated implement, and the attachment power source or the energy storage device.Type: GrantFiled: November 26, 2013Date of Patent: March 22, 2016Assignee: Deere & CompanyInventors: Christopher D.

Patent number: 9228322Abstract: A drive and control system is provided for a towing vehicle pulling a towed implement, such as a tractor pulling a scraper. The drive system includes a diesel engine which drives a generator for generating electric power. A tractor axle drive motor is connected to driven wheels of the tractor through a transmission. An assist drive motor is drivingly connected to driven wheels of the scraper. A power distribution unit controls distribution of electric power from the generator to the tractor and implement assist drive motors. A control unit controls the power distribution unit as a function of an operator set power split, and other sensed parameters. A one-way clutch prevents over-speed of the assist drive motor.Type: GrantFiled: August 20, 2013Date of Patent: January 5, 2016Assignee: DEERE & COMPANYInventors: Gary S. Keys, II, John W. Regenauer, Matthew J. Harris, Brian A. Rodrigue, Clayton P. Neumann, Zachary Kail, Joe L. Schutte

Patent number: 9037346Abstract: A steering control system is disclosed for a vehicle train with a tow vehicle, a first towed vehicle with at least one ground-engaging member, and a second towed vehicle. A steering assembly may be configured to control steering of the at least one ground-engaging member. One or more sensing devices may be configured to determine orientation information for one or more of the tow vehicle, the first towed vehicle, and the second towed vehicle, during operation of the vehicle train. A steering correction may be determined for the second towed vehicle based upon the determined orientation information. The steering correction may be applied for the second towed vehicle by controlling the steering assembly to steer the first towed vehicle.Type: GrantFiled: October 31, 2014Date of Patent: May 19, 2015Assignee: Deere & CompanyInventors: Gary S. Keys, II, Christopher A. Myers, Craig A. Puetz, Andrew K. Rekow, Alan D. Sheidler, Noel W. Anderson
