Abstract: A finishing attachment for a tillage implement has a support arm configured to mount to the frame so that a long dimension of the support arm extends in a fore-aft direction of the implement. A cross-bar having a long dimension extending transverse to the fore-aft direction is coupled to a free end of the support arm. A roller basket is mounted to the cross-bar for rotation with respect to the cross-bar. A pivot bracket couples the free end of the support arm to the cross-bar. The pivot bracket forms a pivot axis extending substantially in the fore-aft direction of travel about which the roller basket pivots.

Abstract: A harrow attachment for a tillage implement includes a harrow drawbar mounting at least one rank of harrowing tools. A pivot link pivotally couples the harrow rank to the drawbar so it can trip by pivoting upward toward the drawbar from a home position in which the harrow rank is farthest away from the drawbar. A downforce spring is coupled to the drawbar and in a variable length state when the harrow rank is tripped to apply a return biasing force to the harrow rank. An adjustment mechanism couples the spring to the harrow rank and/or the pivot link in one of a plurality of adjustment locations in each of which the harrow rank is in the home position and the spring is in a fixed length state in which the biasing force is removed.

Abstract: A harrow attachment for a tillage implement has a harrow drawbar, configured to mount to a frame member of the tillage implement, and at least one harrow rank having a rank bar supporting a plurality of harrowing tools oriented to extend away from the rank bar. An anti-tangle bracket assembly has a first pivot link coupled to the harrow drawbar and a second pivot link pivotally coupled to the at least one harrow rank. The first and second pivot links pivot about pivot axes with respect to one another within a pivotal range of movement of the at least one harrow rank from a first, extended position to a second, tripped position.

Abstract: A compact tillage implement has a frame supported by front and rear frame wheels. A front rank is mounted to the frame between the wheels with respect to a direction of travel to move a front plurality of tools with respect to the frame from a retracted orientation to an extended orientation. A rear rank is mounted to the frame between the wheels with respect to the direction travel to move a rear plurality of tools with respect to the frame from a retracted orientation to an extended orientation. The rear rank is spaced behind the front rank along a reference line. The front and rear plurality of tools are movable with respect to the frame independently of the other of the front and rear plurality of tools while the frame is in working orientation in which the frame is at a substantially fixed pitch with respect to the ground.

Abstract: A drawbar for finishing attachments is arranged to attach to a fore-aft frame member of a tillage implement. The drawbar has a saddle with spaced apart side walls defining a channel configured to receive the frame member. When the frame member is received in the channel, the side walls of the saddle overlap side walls of the frame member and extend in the fore-aft direction rearward of an end of the frame member. The side walls of the saddle and the frame member have mounting openings that align along a lateral direction transverse to the fore-aft direction.

Abstract: An agricultural implement has a closing disk assembly for closing furrows along a section of ground. The closing disk assembly has a pair of closing disks attached to opposite sides and opposite ends of a walking beam. The closing disks are offset from a reference plane of the closing disk assembly. The walking beam is rotatably coupled to the closing disk assembly through a rocker assembly, a support arm, and a mounting assembly. The walking beam may rotate relative to the rocker assembly to account for variations in the angle of the ground relative to the disks.

Abstract: An agricultural implement and attachment are described for soil conditioning. The implement may include an implement frame, with the attachment configured to be towed by the implement frame. A pressurized fluid circuit may be configured to control one or more actuators, in order to provide lifting or lowering force to the attachment. The attachment may include a leading frame and a trailing frame, each configured to support a set of agricultural tools. The trailing frame may be mounted to the implement frame via the leading frame.

Abstract: A C-spring contains an inner spring that is spaced apart from the outer primary spring. In one example usage, the upper and lower legs of the C-spring have rear regions respectively configured for being mounted to a tubular frame tool frame member of a ground working implement, such as a disk, and to a bearing housing.

Abstract: A row cleaner device for a furrow forming row unit includes a support arrangement with a parallel linkage having a single acting hydraulic cylinder connected between upper and lower links. The cylinder extension is controlled by a hydraulic circuit to provide adjustable down pressure to maintain consistent operation of the cleaner devices in varying ground conditions. A tensioning device such as a spring extending generally parallel to the cylinder acts to retract the cylinder. A blocking valve can be closed to maintain the cleaner device in the raised position and can lock the cylinder in any desired extended position. An energy storage device such as a spring compressed between the cylinder and one of the links permits limited vertical movement of the linkage without change of cylinder extension to protect the device and accommodate obstacles and ground surface irregularities in the path when the cylinder is locked in position.

Abstract: A seeding device principally for no-tillage seeding conditions comprises a drag arm carrying two disk blades and transmitting the necessary forces thereto to cut through crop residues at the ground surface and to open a furrow for seed placement in the soil. The smaller disk is oriented vertically, whereas the larger disk extends at a compound angle from a lower front contact point between the two disks which thus define a V-shaped opener. The larger disk is angled relative to both the direction of travel and to a vertical axis to cut through residues and the soil and to displace a volume of soil for forming a trench. The smaller disk retains soil on a side of the furrow to allow a tube to deliver seeds therein. The smaller blade can also cut residues at the point of contact between the two disks to avoid trash buildup thereat.

Abstract: A hydraulic downpressure system for use on no-tillage seeders allows for a constant downward force to be applied on seeding tools operating in highly variable soil surface conditions in order to keep a uniform seeding or planting depth. Raising and lowering of the seeding units can also be achieved with this hydraulic system. A double acting hydraulic cylinder is principally used having its rod end connected to one or two seeding units. A hydraulically operated two-way mode selection valve provides system shifting between both modes involved. The first mode is used when transporting the seeder on roads and to operate the seeding tools in the field. Control is then provided by a three-way directional valve mounted to an external hydraulic power supply, such as an agricultural tractor. Raising and lowering of the seeding tools can be achieved when operating in this mode. A second mode is involved when the seeding tools are working into the ground to sow seeds.
