An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.

A row unit assembly may generally include a clamp mount configured to be coupled to a frame member of an agricultural implement. The clamp mount may include a first clamp member and a second clamp member pivotally coupled to the first clamp member. The first clamp member may include a first clamp wall spaced apart from a second clamp wall of the second clamp member such that the frame member is clamped between the first and second clamp walls. In addition, the second clamp member may include a flange extending outwardly relative to the second clamp wall such that the flange overlaps the frame member along at least a portion of a top side of the frame member. Moreover, the row unit assembly may include an agricultural row unit including at least one support arm pivotally coupled to the clamp mount.

A coulter assembly (10) includes a rotatable coulter blade (12) and a supporting assembly (14) having a parallel linkage arm assembly (34) and an active piston and cylinder assembly (58). The assembly (14) serves to maintain the blade (12) at a depth of at least about four inches, in order to prevent clogging of the assembly (10) during use.

An agricultural tillage implement including a first frame configured to be moved in a travel direction, at least one second frame coupled with the first frame, at least one rolling basket assembly coupled to the at least one second frame, at least one actuator pivotally connected to the at least one second frame, and a pressure control system operatively connected to the at least one rolling basket assembly. The pressure control system includes at least one sensor coupled to the at least one rolling basket assembly for sensing a load exerted on the at least one rolling basket assembly by a ground surface and providing a downward pressure measurement signal. The pressure control system also includes a controller in communication with the at least one sensor and configured to control the adjustable downward force applied by the at least one actuator.

An agricultural system includes a frame configured for attachment to a leading tow bar of a towing vehicle, and at least one roller device attached to the frame and extending between two adjacent parallel strip positions. The roller device is configured to crush standing residual plant matter in the field. The system further includes a fertilizer opener disk attached to the frame and which is configured to prepare, at least in part, a furrow for receiving a fertilizer. The system also includes a fertilizer injector attached to the frame and which is configured to deposit the fertilizer into the furrow in a trailing position relative to the fertilizer opener disk.

A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

A system for adjusting down pressure loads on a harrow of an agricultural implement may include a base hitch member and an upper tow arm pivotally coupled to the base hitch member. First and second linkage arms may pivotally couple to the upper tow arm. A lower support arm may pivotally couple to the first and second linkage arms. A plurality of ground engaging elements may be supported on the lower support arm. A tensioner assembly may include an actuator coupled between the base hitch member and the lower support arm. The actuator may include an actuator rod that extend and retract to adjust a relative distance between the base hitch member and the lower support arm. The actuator may regulate a down pressure applied on the plurality of ground engaging elements by adjusting the relative distance between the base hitch member and the lower support arm.

A coulter assembly for an agricultural implement. The coulter assembly includes a support structure and a disc blade rotatably mounted to the support structure. The coulter assembly also includes a spring assembly coupled to the support structure and configured to urge the disc blade into soil. The spring assembly includes a variable rate spring.

A lock assembly is provided for a row planter unit to maintain the unit in a raised transport position and to relieve stress on the hydraulic system of the planter unit. The lock assembly includes a lock arm pivotally mounted to the bracket assembly of the row planter unit for selective receipt in a notch or detent on the mounting plate or mast of the bracket assembly so as to retain the row unit in the raised transport position. The lock arm can be disengaged from the bracket assembly notch or detent, such that the planter unit can be lowered to the field use position.
