A ground opener for an agricultural implement. The ground opener comprising an opening disc, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. At least a portion of each of the bars is orientated at an offset angle with respect to a direction of travel of the agricultural implement.

A mobile machine includes a frame, and a set of wheels supporting the frame. The mobile machine also includes a set of ground-engaging tools mounted to the frame that are movable relative to the wheels to change a depth of engagement of the ground engaging-tools with ground over which the mobile machine travels. A sensor senses the ground surface over which the mobile machine is traveling. The sensor can do this by sensing the position of a ground-following device having a proximal end coupled to the frame and a distal end configured to engage a surface of the ground and follow the surface of the ground as the mobile machine moves in a direction of travel, or by sensing the surface of the ground behind a surface cleaning device that exposes the surface of the ground to the sensor.

In one aspect, a system for determining soil roughness of a field across which an agricultural implement is being moved may include a tool configured to perform a tillage operation on soil within the field as the agricultural implement is moved across the field. The system may also include a sensor configured to detect a parameter associated with an acceleration of the tool. Furthermore, the system may include a controller communicatively coupled to the sensor, with the controller configured to determine a soil roughness characteristic of the soil based on measurement signals received from the sensor.

A hydraulic system including a supply line, an implement-based control valve, an override valve supported by the implement, and a bypass line. The control valve is fluidly coupled to the supply line and configured to regulate a flow of pressurized hydraulic fluid supplied through a downstream actuator line to a hydraulic actuator of the implement. The override valve is fluidly coupled to the actuator line downstream of the control valve and includes a supply position at which the flow of pressurized hydraulic fluid from the control valve passes through the override valve to the hydraulic actuator. The override valve is actuatable to at least one override position at which the flow of pressurized hydraulic fluid from the control valve is cut-off. The bypass line is fluidly coupled between the supply line and the override valve such that a portion of the pressurized hydraulic fluid flows to the hydraulic actuator.

A tilling machine includes a frame having a jump arm frame unit and a 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 assembly for a tilling machine includes a jump arm and a disc hub assembly. The jump arm has a first end coupled to a frame unit of the tilling machine and a second end opposite the first end. The disc hub assembly includes a an arm end configured to be fixedly secured to the second end of the jump arm, and an opposing disc end. A first plane defined by the arm end of the disc hub assembly is arranged in non-parallel relation with respect to a second plane defined by the disc end of the disc hub assembly.
