Abstract
An implement for working an agricultural field includes a frame and a plurality of row units carried by the frame. Each row unit includes a subframe trailing the frame and connected to the frame by an upper link and a lower link, at least two different ground-engaging tools carried by the subframe, and at least one pneumatic actuator configured to change a length of the upper link or the lower link to keep the ground-engaging tools in contact with ground. A method includes pulling the implement through the agricultural field, maintaining a selected pressure in the pneumatic actuator, and maintaining the ground-engaging tools in contact with the agricultural field.
