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.
