| 20100084149 | PIVOTING GAUGE WHEEL - Embodiments of the invention provide an innovative arrangement to control the height of ground engaging tools located on agricultural implements via gauge wheel assemblies, particularly for supporting and adjusting the height of winged extensions of the implement frame. The gauge wheel assemblies may provide an adjustment assembly in the form of a screw jack, which can be coupled to a support bracket that is attached to the implement frame and also coupled to a support tube that is coupled to a gauge wheel via pivot assembly and a bracket. The bracket and support tube may be coupled at discrete positions according to the height adjustment of the screw jack via pins and holes in the bracket and tube. When coupled, the pins and holes of the support bracket and tube may reduce the load of the winged extensions on the screw jack mechanism. | 04-08-2010 |

| 20120073843 | SUSPENSION DEVICE FOR A WORK VEHICLE - A suspension device for a work vehicle is capable of not only providing improved ride quality during nonoperational traveling such as on-site movement over uneven terrain, but also ensuring stable driving power during operational traveling such as an excavation operation on uneven terrain. The suspension device | 03-29-2012 |
| 20130175063 | DEPTH CONTROL SYSTEM - A depth control system for a frame mounted to a movement system is provided. The frame is mounted such that the frame can be raised and lowered in relation to the movement system by a height adjustment mechanism. The depth control system includes a depth control arm connected to the movement system, a height adjustment mechanism, and a mechanical stop. The height adjustment mechanism is configured to engage with the depth control arm to adjust the height of the frame. The mechanical stop is configured to engage with the depth control arm to prevent the frame from moving in at least one direction with respect to the movement system and disengage from the depth control arm when the height of the frame is being adjusted. | 07-11-2013 |
| 20150129259 | ROCKER LINK LIFT SYSTEM - A lift system for an implement has the lift cylinder near the implement front end. A rocker link with three vertically spaced pivot holes is located rearward of the cylinder and connected to an implement frame by a pivot pin through the center one of the holes. The lift cylinder is connected to the lower pivot hole while two further links are connected to the top hole and extend longitudinally away from one another to control raising and lowering of front and rear wheels respectively. As the cylinder extends and retracts, the rocker pivots causing the front and rear wheels to raise and lower in synchronism with each other. Fore and aft leveling adjustment may be achieved by including a turnbuckle in one of the further links to vary the length thereof relative to the other. | 05-14-2015 |

| 172421000 | Plural ground supports vertically adjustable relative to each other and the frame | 1 |
| 20150053440 | TILLAGE IMPLEMENT WITH ENHANCED FRONT WHEEL SUSPENSION - A tillage implement has a main frame provided with power-actuated lift wheels at the rear of the frame and a pair of gauge wheels at the front of the frame. A linkage system connecting the rear wheels with the front wheels transmits the raising and lowering motion of the rear wheels to the front wheels so that the main frame remains level as it is raised and lowered by all of the wheels in unison. However, a coupling that uses an equalizing rocker bar between front and rear linkages of the linkage system permits either of the front wheels to be raised or lowered in a non-corresponding manner relative to the other front wheel as differences in terrain contour are experienced between the two front wheels. During such non-corresponding shifting of the front wheels relative to one another, movement of the two front wheels is in equal amounts but opposite directions to maintain both front wheels engaging the ground at all times and equally sharing the load. | 02-26-2015 |

| 20100258325 | Walking Beam Assembly and Lift System for Tillage Implements - A tillage machine has an undercarriage that utilizes a triple axle walking beam wheel assembly for each load-supporting wheel assembly of the center section of the machine. Hydraulically powered lift arms are connected with the wheel assemblies to raise and lower the chassis of the machine as the wheel arms are swung downwardly and upwardly relative to the chassis. Each wheel assembly includes a primary walking beam pivoted to the lower end of the wheel arm, and a secondary walking beam pivoted to the rear end of the primary beam. A single front wheel is disposed at the front end of the primary beam, while a pair of wheels are disposed on the secondary beam on opposite fore-and-aft sides of the pivot connection with the primary beam. An abutment on the wheel arm engages a stop on the primary beam upon downward rotation of the wheel arm by a predetermined amount relative to the chassis such that continued downward movement of the wheel arm causes load to shift partially off the front wheel and onto the rear wheels. | 10-14-2010 |
| 20150351311 | DEPTH ADJUSTMENT FOR CONTROLLING PLANTING DEPTH - A depth adjustment for an agricultural seed planting implement has a register with notches and a handle that engages pairs of the notches to control the depth of a seed trench opening assembly. The handle has a first handle orientation and a second handle orientation for each pair of notches and provides two different depth settings for each pair of notches in the register. | 12-10-2015 |
| 172424000 | Spring assisted | 1 |
| 20100200256 | Marker Assembly Having Spring Linkage To Limit Momentum In Marker Assembly During Marker Assembly Deployment - A marker assembly includes a first linkage section interconnected to a second linkage section by a pivoting joint. The pivoting joint also includes a spring linkage that limits momentum in the second linkage section before a marking disc carried by the second linkage section engages the ground. The spring linkage may be comprised of a spring that is retained by a pair of washers within a housing or canister. A linkage rod passes through the canister and has a set of nuts that are sized to catch the washers. Thus, if the spring linkage is compressed or extended, the catch nuts press up against the washers thereby compressing the spring. By compressing the spring, a force is applied in the opposite direction as the momentum in the marker assembly, which reduces the collective momentum in the marker assembly during deployment. | 08-12-2010 |
