A disk for use with a tillage machine includes a body portion rotatable about an axis of rotation. The body portion has a circumferential edge and a concavity with a first radius defined from a point on the axis of rotation. A hub portion is continuous with the body portion and presents an abutment face having a concavity with a second radius defined from a point on the axis of rotation. An aperture extends through the abutment face and is centered about the axis of rotation.

A disk blade having a circular blade body of a first base material of a first hardness and having top and a bottom surfaces and an outer edge extending around the blade body. At least one clad bead extends circumferentially about the blade body on the bottom surface adjacent the outer edge of a second hardness greater than the first hardness of the base material. Various bead patterns are possible.

A system for adjusting the spacing between ground engaging tools of an agricultural implement may include a plurality of ground engaging tools including a first end tool, a second end tool, and at least one intermediate tool positioned between the first and second end tools, with an adjustable ground engaging width being defined between the first and second end tools. The system may further include a biasing element positioned between each respective pair of adjacent engaging tools and configured to apply a biasing force against its respective pair of adjacent tools such that an inter-tool spacing between each respective pair of adjacent tools is maintained substantially uniform across the plurality of ground engaging tools as the ground engaging width is adjusted.

An extended highspeed rigid hub (EHRH) combined with a specific double roller taper bearing and tapered head bolt coupled with a coulter blade create a coulter blade assembly of great strength which functions to minimize flex at the circumference of the coulter blade. The EHRH maintains inner as well as outer bosses which support both inner and outer attachment points for the taper headed bolts to provide rigidity to the coulter blade. The double roller taper bearing adds to the rigidity equation by mitigating axial as well as radial forces exerted on the coulter blade. The coulter blade assembly, when coupled as one element to an implement, creates a rigid furrowing device capable of precise furrow construction in many challenging soil conditions.

In one aspect, a system for rotationally driving ground engaging tools of an agricultural implement may include a rotational actuator configured to rotationally drive a ground engaging tool of the implement about a rotational axis. A controller may be configured to determine a current ground speed of the implement based on data received from a sensor. Moreover, the controller may be further configured to determine a rotational output for the rotational actuator based on the current ground speed of the implement such that the tool rotates at a predetermined rotational speed relative to soil within a field. In addition, the controller may be configured to control the operation of the rotational actuator such that the actuator provides the determined rotational output to the tool while the tool is disposed at a working position relative to a soil surface of the field.

A system for de-plugging rotating ground engaging tools of an agricultural implement includes first and second ground engaging tools spaced apart from each other such that a flow gap is defined between the tools, a rotational actuator configured to rotationally drive the tools about a rotational axis, a sensor configured to capture data indicative of material accumulation within the flow gap defined between the tools, and a controller configured to determine when the tools are experiencing a plugged condition based on the data received from the sensor. Additionally, in response to the determination that the tools are experiencing the plugged condition, the controller is further configured to control an operation of the rotational actuator such that the tools are rotationally driven while such tools are disposed at a working position relative to a soil surface of a field.

In one aspect, a system for detecting accumulations of field materials between ground engaging components of an agricultural implement may include first and second ground engaging components configured to rotate relative to soil within a field as the implement is moved across the field. The first and second ground engaging components may be spaced apart from each other along an axial direction of the shaft. The system may also include a sensor configured to detect field materials within a detection zone defined directly between the first and second ground engaging components and above the axis of rotation in a vertical direction of the agricultural implement. Furthermore, the system may include a controller communicatively coupled to the sensor, with the controller configured to determine a parameter associated with an accumulation of the field materials between the first and second ground engaging components based on data received from the sensor.

A trench closing assembly having an actuator for applying a force to the trench closing assembly in which the force is divided between closing wheels and a press wheel disposed rearward of the closing wheels.
