20140283493 | Rotary Disk Header with a Roller for Transferring the Crop Supported by a Center Bearing - A crop header has generally horizontal flail disks mounted on a cutter bar for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening. A crop converging system includes two over-shot auger elements defined by a common rotary member with an auger flight carried thereon arranged generally longitudinal of the cutter bar so as to carry the cut crop longitudinally of the cutter bar to the entrance opening. The common rotary member includes two portions connected at a center location driven at one end and supported at the center location by a bearing and support plate connected to the cutter bar attached to one portion and a universal joint between the end of the supported portion and the other portion to allow flexing of the cutter bar to be transmitted though the universal joint. | 09-25-2014 |
20140138166 | Speed and Steering Control of a Hydraulically Driven Tractor - A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. Each driven wheels is driven by a hydraulic motor with a continuous adjustment of the motor displacement, with the motor being driven by a pump also having continuous displacement. The motor displacement is controlled by an electronic controller in response to stroking of the speed control lever to manage the displacement to provide required drive torques at different points in the stroke. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information which controls the steering by differentially adjusting the displacement of the motors so that the automatic steering is independent of the manual steering which controls the pumps. | 05-22-2014 |
