20090056298 | Over-Retraction Limiter for the Fingers of a Retracting Finger Auger Mechanism - A retracting finger auger assembly is provided with a limiter inside the auger tube of the assembly that is disposed to make temporary engagement with the internal eccentrically offset finger shaft of the retracting finger mechanism in the event of flexure of the finger shaft beyond a predetermined amount. In a preferred embodiment, the limiter comprises a transverse, annular member with a guide ring of anti-friction material circumscribing the finger shaft, the member being secured to the interior surface of the auger tube for rotation therewith. The anti-friction guide ring is normally maintained slightly out of contacting engagement with the finger shaft, but is disposed to be engaged as necessary by the flexing shaft to limit such flexing and prevent over-retraction of the retracting fingers. | 03-05-2009 |
20090094957 | Combine Harvester Draper Header Having Flexible Cutterbar - A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester.

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 |

20120151892 | SWIVEL DRAWBAR HITCH - In one embodiment, a swivel drawbar hitch comprising a first cradle having a first pivot mechanism located ahead of a connection between a drawbar and the swivel drawbar hitch, the swivel drawbar hitch further comprising an elongated second cradle coupled to the first cradle and further having a second pivot mechanism, the first cradle pivotable about a horizontal axis of the swivel drawbar hitch, the elongated second cradle pivotable about a longitudinal axis of the swivel drawbar hitch. | 06-21-2012 |
20120174553 | Header with Elevated Doors for Tall Robust Crops - A header assembly supported on the front of a windrower includes a header configured to process crop material standing in a field and a lean bar as the leading element for contacting crop material and preparing the crop material for processing by the header. The lean bar is positioned forward of the header so that the lean bar is the forward-most element of the header assembly. The header assembly has a plurality of cutting elements arranged in a line transverse the header. A cutter bar shield door is positioned to an elevated position such that a forward most point of the cutter bar shield door is above a rearward most point of the cutter bar shield door. The forward most point of the cutter bar shield door lies on or behind a line drawn between the forward edge of the lean bar and a rotational center of the cutting elements. | 07-12-2012 |
