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.

Abstract: A downforce system adjusts the amount of downforce being applied to a row unit of an agricultural implement. The downforce system is controlled to increase or decrease the force on the row unit. A load is sensed at the row unit and compared to either or both of a user defined target and a lower threshold that can be based, at least in part, upon a percentage of a value. When the load is determined to be below the lower threshold, the user defined amount is increased at a rate of change until the load is above the threshold, at which point the increase is stopped, and reduced, if necessary.
