Abstract
Agricultural planting implements, as well as other ground-engaging implements, can utilize supplemental force assemblies to provide up and/or down force at the row or rows of the implements. The force can be used to overcome changing field conditions, obstructions, as well as changing particulate amounts and weights carried by the rows of the implements, and the implement itself. The up force can be set at system pressure, or can include control valves at each of the row units to control the amount of up force provided. The down force can be controlled by control valves at each of the row units, and can be used to overcome the up pressure or provide a designated amount of down force to the row.
