A control system for a work vehicle of a work vehicle system is provided that includes at least one controller including a memory and a processor. The at least one controller is configured to determine an attitude of a working surface of an implement relative to a field. In addition, the at least one controller is configured to generate evenly spaced swaths of the field, each swath having a center line. Further, the at least one controller is configured to determine target altitudes for points along the center line for a respective swath. Even further, the at least one controller is configured to adjust a depth of the working surface of the implement relative to the field to meet the target altitudes at respective points while the work vehicle moves along the field.

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.

In one aspect, a shank assembly for an agricultural implement may include a shank and a biasing element configured to exert a biasing force on the shank. The shank assembly may also include a reversible mounting plate defining a mounting aperture offset from a centerline of the reversible mounting plate such that a position of a second mounting location of the biasing element relative to a first mounting location of the biasing element differs depending on whether the reversible mounting plate is provided in a first orientation relative to the biasing element or a second orientation relative to the biasing element. The biasing element may exert a first biasing force on the shank when the reversible member is oriented in the first orientation and a second, different biasing force on the shank when the reversible member is oriented in the second orientation.

A digging assembly (10) for a plough. The digging assembly (10) has a digging blade assembly (17) that is moved through the soil to form a slot, and a closing tool assembly (29) that forms a seed bed by partly closing the slot formed by the digging blade assembly (17). Following the closing tool assembly (29) is a seed boot (57) that delivers seed to the seed bed formed by the closing tool assembly (29).
