Abstract
A self propelled soil working machine includes a tool carrier which is actively adjustable to provide variable downward force on a soil working tool via a suspension element which is further passively responsive to accommodate motion of the tool in response to external force. The tool carrier is configured to adjust the working depth and pitch of the tool.
