A control system for an implement hitch of an agricultural vehicle, wherein the hitch is mounted to the vehicle and includes one or more hydraulic cylinders or other actuators operable to raise and lower the hitch between minimum and maximum heights relative to the vehicle and hold the hitch static at one or more heights between the minimum and maximum heights. The control system includes a rocker control device having a first operating position and being movable in a first direction to a first limit position and in a second direction to a second limit position. An electronic control unit connected to the rocker control device is configured to control operation of the or each of the hydraulic cylinders or actuators and thereby control raising and lowering of the hitch in response to user operation of the rocker control device. The ECU is operable to control raising and lowering of the hitch according to one of two or more control modes, and to switch between said control modes in response to a predetermined first actuation operation of the same rocker control device.

A planting system including a plurality of seeding row assemblies, each having components maintained at a controlled elevation. The seeding row assembly includes a tillage row unit controlled to maintain a desired elevation relative to a seeding row unit, the seeding row unit being configured to passively follow the local terrain. Each seeding row assembly can include two position sensors that generate signals corresponding to the elevation of the seeding row unit and the ground engagement attachment, respectively, or a differential positon sensor that generates signals corresponding to the difference in the elevations. Various embodiments include a local closed loop controller that adjusts elevation of the tillage row unit relative to the seeding row unit to a desired set point. In some embodiments, the down force of the seeding row unit is actively controlled.
