Abstract
One or more techniques and/or systems for application of a supplemental downward force to a ground working implement. A mechanical advantage from a lever arm can be utilized to apply supplemental downforce to a ground working implement. A biasing force can be applied to the lever arm by a spring assembly at various locations. Moving the spring assembly along the lever arm can vary the amount of downward force applied by the lever arm to ground working implement. In some implementations, moving the spring assembly to a different end of the lever arm applies an upward force to a coupled ground working implement.
