Abstract: The disclosed apparatus, systems and methods relate to devices, systems and methods for the selective application of down pressure or downforce to a row unit. Each row unit has a dual-action actuator which is in fluidic communication with the hydraulic system for independent control of the supplemental downforce. The pressure line can be directly routed to the lift chamber for a constant supply of up pressure, with down pressure selectively applied to the down chamber for accurate control of the supplemental downforce system.
