A tilling machine includes a frame having a jump arm frame unit and a plurality of jump arm assemblies supported along a length of the jump arm frame unit such that a lateral gap is defined between each adjacent pair of jump arm assemblies of the plurality of jump arm assemblies. Additionally, the tilling machine includes a plurality of jump arm spacers, with each jump arm spacer being provided in operative association with a clamp unit of a respective jump arm assembly of the plurality of jump arm assemblies to maintain the lateral gap between each adjacent pair of jump arm assemblies.

A jump arm apparatus for a tilling machine includes a jump arm frame unit having a triangular transverse cross-section and a plurality of jump arms assemblies coupled to the jump arm frame unit. Each jump arm unit includes a jump arm having first and second ends, with the first end coupled to be coupled to the jump arm frame unit via a clamp unit and the second end configured to be coupled to a tilling disc.

An agricultural implement includes a plurality of ground-engaging tools configured to modify a surface configuration of an agricultural field and a hydraulically-controlled subsystem configured to modify an operating angle of the plurality of ground-engaging tools. The agricultural implement also includes a sensor coupled to the hydraulically-controlled subsystem configured to generate sensor signals indicative of a current operating angle of the plurality of ground-engaging tools. The agricultural implement also includes an implement control system configured to receive the sensor signals from the sensor to determine the current operating angle of the plurality of ground-engaging tools, and, upon determining the current operating angle is to be changed to a new operating angle, generate control signals for the hydraulically-controlled subsystem to modify the operating angle of the plurality of ground-engaging tools from the current operating angle to the new operating angle.

A tillage control system for a plurality of row units having an implement and being connected to a frame. The system includes a hydraulic system having fluid, a supply port and a drain port. A plurality of control subsystems are fluidly coupled with the supply port and the drain port. Each control subsystem is coupled with one of the plurality of row units and include a control valve and an actuator fluidly coupled to the control valve. The system further includes a controller communicatively coupled with each of the control valves to independently operate each actuator to raise and lower each implement of the plurality of row units relative to the frame.

In one aspect, a system for monitoring the condition of a seedbed within a field may include a seedbed tool configured to ride along a seedbed floor as an implement frame is moved across the field. The system may also include an actuator configured to adjust the position of the seedbed tool along a lateral direction relative to the implement frame such that the seedbed tool traverses a lateral swath of the seedbed floor along the lateral direction. Furthermore, the system may include a seedbed floor sensor configured to detect the position of the seedbed tool relative to the implement frame. The position of the seedbed tool may be indicative of a profile of the lateral swath of the seedbed floor as the seedbed tool rides along the seedbed floor with movement of the implement frame in the forward travel direction.

An apparatus, which may be a tillage apparatus, may have a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.
