20090107096 | Drive System for an Agricultural Machine with a Floating Work Tool - A drive system for agricultural implements having at least one floating head and a tongue that may be disposed at various angles relative to a longitudinal angle of the implement. Two swivel gearbox assemblies are used, each comprising a first 90° gearbox rigidly attached to the implement and a second 90° gearbox that is permitted to rotate about an axis passing through one of its shafts and one of the first 90° gearbox's shaft. Because the tongue angle is variable, the drive shafts for driving the implement must take on a plurality of angles. The swiveling gearbox assemblies allow variable angles at the tongue and at the header. | 04-30-2009 |
20090107097 | Four-Bar Linkage for Suspending a Header for an Agricultural Implement - A suspension system for agricultural implements having at least one floating head using a four-bar linkage and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction. A main frame is provided to which the ground engaging wheels are attached. A sub-frame is connected to the main frame via the four-bar linkage. The sub-frame is pivotally attached to the arms of the four-bar linkage by spherical bearings. | 04-30-2009 |

20100192534 | Four-Bar Linkage for Suspending a Header for an Agricultural Implement - A suspension system for agricultural implements having at least one floating head using a four-bar linkage and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction.

20110017480 | Folding Frame for an Agricultural Implement - A folding frame for an agricultural implement such as a wheel rake. The frame includes ground engaging wheels and two toolbars foldable for operation and for transport. The folding frame is provided flexibility to conform to uneven surfaces, yet stability against the torques and forces of operation. A slidable tongue provides folding action between the transport position and the operating position. A spacing between rear ends of the two toolbars may be altered hydraulically for wider or narrower windrows. A novel caster wheel provides support for the toolbars and is located so that the implement's transport position is narrower than the prior art's. | 01-27-2011 |
20110047948 | Self-Leveling Four-Bar Linkage for Suspending a Header of an Agricultural Implement - A suspension system for agricultural implements having at least one floating head using a four-bar linkage, and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction. A main frame is provided to which the ground engaging wheels are attached. A sub-frame is connected to the main frame via the four-bar linkage. The sub-frame is pivotally attached to the arms of the four-bar linkage by spherical and cylindrical bearings. The lower linkage arms of the four-bar linkage are maintained in compression while the upper linkage arms are maintained in tension. Due to the compression and tension in the linkage arms, the floating head will self-level in the transverse direction when raised, yet allow the header to float during operation. | 03-03-2011 |
20110219738 | Automatically Steered Gearboxes for an Implement with a Pivoting Tongue - A mower is suspended from a frame and includes a header with a cutter. A tongue is pivotally connected to the mower frame and is moveable with respect to the frame by a hydraulic cylinder. At the front of the tongue is a front gearbox rigidly attached to the tongue. The front gearbox transmits rotary power from the power take off of the tractor to a rear gearbox pivotally attached the header and from the rear gearbox rotary power is passed on ultimately to the rotary cutting units. Pivoting of the rear gearbox is controlled by a steering connection operatively attached between the front and rear gearboxes. | 09-15-2011 |
20110219739 | Four-Bar Linkage for Suspending a Header for an Agricultural Implement - A suspension system for agricultural implements having at least one floating head using a four-bar linkage and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction. A main frame is provided to which the ground engaging wheels are attached. A sub-frame is connected to the main frame via the four-bar linkage.

Because the tongue angle is variable, the drive shafts for driving the implement must take on a plurality of angles. The swiveling gearbox assemblies allow variable angles at the tongue and at the header. | 09-29-2011 |

20130074709 | Baler Attachment for Optionally Changing the Orientation of Bales Being Released From a Baler - A bale turning apparatus for attachment to a baler to generally align the cylindrical of the bales in each row as the bales are released from the baler. Using the disclosed invention, the bales are essentially turned ninety degrees from the orientation of bales from the position that they are typically released from a round baler. By accomplishing this general alignment of the cylindrical axis of each bale in each row, when baling corn stover or other row crops, the bale loading operation can later be done more efficiently by driving down the rows in the same direction as the combine and baler have traveled. | 03-28-2013 |
