20090158699 | Modular Rotary Cutterbar - A modular rotary cutter bed is formed by a series of essentially identical cutter modules mounted end-to-end along the length of a common support beam. Guards for the cutters of the modules are arranged such that each guard overlaps and bridges the seam between an adjacent pair of modules so as to increase the structural rigidity of the cutter bed. Each guard is attached at its front end to the noses of a pair of adjacent modules and at its rear end to the support beam to increase structural integrity in all directions. A second embodiment does not utilize a common support beam for the modules but instead relies upon the interconnections between adjacent modules and bridging overlap of the guards to rigidify the cutter bed. | 06-25-2009 |
20110146219 | Wide Cut Rotary Harvester Having Helper Roll With Auger Flighting - In an example embodiment, a harvesting header includes a helper roll having at auger flighting configured to move crop material laterally inward. The auger flighting may be outboard of a crop receiving area. The helper roll may be placed rearward of a cutter mechanism and forward of a conditioning roll of the header. The axis of rotation of the helper roll may be positioned slightly above a cutting plane of a cutting bed so that the auger flighting extends vertically past the cutting plane. In an example embodiment, at least a portion of the auger flights are positioning outboard of a conditioning roll of the header. | 06-23-2011 |
20110146220 | Wide Cut Rotary Harvester With Improved Helper Roll - In an example embodiment a harvesting header has a cutter mechanism to cut crop material, a discharge opening through which the crop material may be discharged, at least one conditioning roll to condition crop material cut by the cutter mechanism that passes through the discharge opening, and a helper roll extending laterally outward of the discharge opening. A support may be provided at the discharge opening for rotatably supporting the helper roll. In one example embodiment the helper roll comprises a first sub-helper roll and a second sub-helper roll that are rotatably coupled to a bearing assembly mounted at the discharge opening. | 06-23-2011 |
20120210693 | Fixed Rotary Knife with Multiple Cutting Surfaces - A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter is ninety degrees out of phase with respect to its adjacent cutters such that the circular paths of travel of the knives of adjacent cutters overlap one another, and adjacent cutters rotate in opposite directions. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. The cutter also includes an attachment device connecting each knife to the knife carrier, and a fixed stop restricting rotational movement of the knife with respect to the carrier about the attachment device. | 08-23-2012 |
20120247709 | METHOD FOR DETERMINING WHEN COOLING SYSTEM IS RESTRICTED - A method for determining when a cooling system for a work vehicle is restricted with debris. A first temperature difference between an inlet and an outlet of a heat exchanger is determined when the airflow though said heat exchanger is substantially unrestricted. When a subsequent temperature difference is less than the first temperature difference by a predetermined amount, the direction of the airflow is reversed to remove debris from the heat exchanger. | 10-04-2012 |
20120274460 | Field Efficiency Gauge - A field gauge includes an indicator for a present value and an indicator for a comparison value of an operating characteristic, such as field fuel efficiency. | 11-01-2012 |
20130042592 | Feeding For Wide Cut Rotary Header Having Helper Roll - In an example embodiment, a harvesting header includes a helper roll having an auger flighting configured to move crop material laterally inward. The auger flighting may be outboard of a crop receiving area. The helper roll may be placed rearward of a cutter mechanism and forward of a conditioning roll of the header. The axis of rotation of the helper roll may be positioned slightly above a cutting plane of a cutting bed so that the auger flighting extends vertically past the cutting plane. In an example embodiment, at least a portion of the auger flights are positioning outboard of a conditioning roll of the header. The helper roll may be supported within the cutting zone and comprised of a plurality of sub-helper rolls. | 02-21-2013 |
20130255214 | Header Flotation System with Computer Control for a Self-Propelled Windrower - In one embodiment, a header control method for an agricultural machine, the method comprising receiving, through a graphical user interface, operator input corresponding to a first set point and a second set point for flotation pressures corresponding to independently controllable first and second header portions, respectively; and automatically causing first and second sets of hydraulic valves to increase or decrease pressure to the first or second header portions to meet or at least approximate the first and second set points, the first and second sets each comprising opposing-action hydraulic valves, the causing responsive to sensed pressure at respective first and second accumulators associated with respective first and second float cylinders. | 10-03-2013 |
