| 172261000 | OVERLOAD SHIFTING | 10 |
| 20080264653 | Overload Protection Device for Agricultural Appliances - Overload protection device for agricultural appliances, such as for example agricultural implements with a joint connecting the agricultural tool to the carrier frame, said joint comprising two joint parts held together by spring load and mutually supporting, of which one is mounted on the agricultural tool and the other on the carrier frame, wherein on both joint parts at least one upper support arrangement and at least one lower support arrangement are arranged spaced from one another, characterised in that the lower support arrangement ( | 10-30-2008 |
| 20120279734 | IMPLEMENT AND ASSEMBLY FOR CARRYING OUT OPERATIONS ON AN AGRICULTURAL LAND - An implement for soil preparation is moved in a direction of travel by a tractor with a three-point linkage. The implement includes an attaching mechanism, a coupling member with three coupling points, a first tool beam which is attached to the coupling member, at least one tool which is supported by the first tool beam, and three coupling elements which are each movably attached to the coupling member in the region of the respective coupling points to connect the coupling member to the attaching means. The first coupling element defines a path of movement for a guided movement of the first coupling point with respect to the attaching means. The second and the third coupling element each define a path of movement for a guided movement of their respective coupling point with respect to the attaching mechanism. | 11-08-2012 |

| 20120325504 | Down Pressure Apparatus - A down pressure adjustment assembly for a disc opener of an agricultural implement includes a rockshaft to which one or more disc opener units are mounted and an actuator that rotates the rockshaft. Rotation of the rockshaft causes the disc opener units to be raised or lowered. When the disc opener units are lowered into a field engagement position, further rotation of the rockshaft will cause compression of down pressure springs for each of the disc opener units. | 12-27-2012 |
| 20130112442 | ADJUSTABLE PACKER WHEEL SEEDING SYSTEM AND METHOD - In one embodiment, a seeding implement includes a frame configured to couple to a tool bar, a parallel linkage coupled to the frame, and a ground engaging tool extending from a shank, wherein the shank is coupled to the parallel linkage. The implement also includes a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned directly behind the ground engaging tool when the ground engaging tool is engaging a soil region. Further, the implement includes an adjustment mechanism configured to shift the packer wheel rearwardly upon the ground engaging tool encountering an obstruction and to shift the packer wheel forwardly after the obstruction has been passed by the ground engaging tool. | 05-09-2013 |
| 20130112443 | ADJUSTABLE PACKER WHEEL SEEDING SYSTEM AND METHOD - In one embodiment, a seeding implement includes a frame configured to couple to a tool bar, a parallel linkage coupled to the frame, and a ground engaging tool extending from a shank, wherein the shank is coupled to the parallel linkage. The implement also includes a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned directly behind the ground engaging tool when the ground engaging tool is engaging a soil region. Further, the implement includes an adjustment mechanism configured to shift the packer wheel rearwardly upon the ground engaging tool encountering an obstruction and to shift the packer wheel forwardly after the obstruction has been passed by the ground engaging tool. | 05-09-2013 |
| 20140076594 | GROUND WORKING APPARATUS - A ground working apparatus has a plow assembly including a frame formed with an attached runner and a plow tool. A linkage assembly couples the frame to a bridle assembly for movement of the plow assembly between raised and lowered positions relative to the bridle assembly. The runner and the plow tool depend downwardly from the frame to concurrently run over and plow, respectively, ground to be plowed along a plowing path ahead of the bridle assembly and the plow assembly, wherein the runner sets the frame of the plow assembly at a fixed elevated position with respect to the ground to be plow. | 03-20-2014 |
| 20150053438 | TILLAGE IMPLEMENT WITH STOP FOR RESILIENT MOUNTING - An agricultural tillage implement including a carriage frame assembly and pull hitch towed by a tractor and secondary frames supported by the carriage frame assembly. The secondary frames support gangs of disk blades for tilling the soil in a travel direction. Bearing hanger assemblies support the gangs of disk blades below the secondary frames through a C shaped resilient element. Stop elements are mounted on the bearing hanger assemblies and to a cross bar to limit deflection of the C shaped elements by abutting some of the secondary frames. | 02-26-2015 |
| 172265000 | Swinging about fixed pivot axis | 3 |
| 20110132627 | RESILIENTLY MOUNTED AGRICULTURAL TOOL AND IMPLEMENT THEREWITH - Disclosed are mounting means for agricultural tools, for example tillage assemblies, that comprise a resilient element and a horizontal pivot axis. This allows upward and rearward deflection of a tillage blade of the assembly in response to impact with obstacles. Tillage implements comprising the foregoing assemblies are also disclosed. In certain embodiments, the assemblies advantageously allow lateral deflection of at least a support arm of the assembly in response to impact with obstacles, which may be enhanced by providing a pivot means of the assembly with a resilient bushing. The resilient element and/or the resilient bushing may comprise elastomeric materials. | 06-09-2011 |
| 20140262375 | INTERCHANGEABLE SHANK TRIP MECHANISM - A tillage apparatus includes a trip linkage selectively configured as a spring biased trip linkage, a spring toggle trip linkage, or a shear bolt trip linkage and mounted between a toolbar bracket and a shank member wherein the trip linkage is selected to allow shaft member to pivot upwardly responsive to variable excessive draft force. | 09-18-2014 |
| 172266000 | Including toggle linkage | 1 |
| 20150129257 | SHEARABLE LINK FOR DISK BLADE PROTECTION - A mechanical coupling arrangement for interconnecting a compression spring assembly and certain working tools such as the disks of an agricultural tillage implement includes a hinge having a pivot axis and first and second arms extending from the pivot axis. Linkage arrangements couple the first hinge arm to the spring assembly and the second hinge arm to the working tools. A shear pin extends between the hinge arms remote from the pivot axis for fixing the angular relationship between the arms so long as the spring compression remains less than a predetermined maximum. Shear pin failure allows one hinge arm to pivot relative to the other when the predetermined maximum tension is exceeded uncoupling the spring assembly from the tools. | 05-14-2015 |
