A cultivator is provided having a tool frame, a mounting bar provided below the tool frame, and a plurality of ground engaging tools connected to and extending below the mounting bar. The mounting bar can be connected to the tool frame by a plurality of mounting brackets and at least one adjustment mounting bracket. The mounting brackets allowing the mounting bar to be moved laterally relative to the tool frame and the at least one adjustment mounting bar allowing for the lateral adjustment of the mounting bar and ground engaging tools relative to the tool frame.

A system for determining material accumulation relative to ground engaging tools of an agricultural implement includes a frame member extending along a first direction, first and second ground engaging tools coupled to the frame member, a sensing arm, a sensor, and a controller. The first and second ground engaging tools are spaced apart from each other in the first direction such that an open space is defined between the first and second ground engaging tools. The sensing arm is aligned with the open space defined between the first and second ground engaging tools and is displaceable, with the sensor being configured to detect displacement of the sensing arm. The controller is configured to monitor the displacement based at least in part on data received from the sensor to determine a presence of material accumulation between the first and second ground engaging tools.

A row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.

System that automates crop maintenance activities, such as cultivating and weeding, with a device that intelligently and independently controls two blades that drag along either side of a crop row using sensors to repeatedly track the position of the blades and of the plants in the row. Blades may be moved in and out independently using an actuator for each blade to contour closely around the individual plants, even if plants or rows vary in their positions, and even if plant sizes and shapes differ. An illustrative system may use a single camera and a processor per crop row; the processor may analyze camera images to locate plant positions and shapes, to plan blade trajectories, and to control blade actuators. The processor may be able to control blade movement precisely to respond quickly to sensor input on changes in plant positions, shapes, and sizes along the row.

A tillage implement has a main frame towed in a forward working direction and toolbar assemblies supported on the main frame. Each assembly has an elongate toolbar member transverse to the forward working direction with tillage units spaced along the toolbar member for working the ground. A pivot supports each toolbar at an intermediate location on the toolbar for angular adjustment about an upright axis relative to the main frame. Followers at opposing ends of each toolbar member are received in respective guides at fixed locations on the main frame such that the followers are slidable within the guides in the forward working direction while restricting rotation of the toolbar member about a longitudinal axis of the toolbar member relative to the main frame. Angular position of each toolbar is controlled by an actuator with an attached mechanical indicator that can be read by an operator.

A tillage implement comprising a frame operably supporting tillage tools, and a soil monitoring system comprising instrumentation operably supported from the frame and disposed to detect soil criteria before, after, or before and after the soil is tilled by the tillage tools. The soil criteria detected is at least one of surface residue criteria, soil clod size criteria, and soil shatter criteria.
