摘要：
A planter row unit is disclosed having an active downforce control system for the closing wheels. This separate control of the downforce pressure for the closing wheels is provided from the row unit downforce control. A single operator input is used to set a desired downforce for all row units. The control system then operates to produce the desired downforce. Alternatively, the control system may display a downforce load to the operator who then manually makes adjustments as desired.
