Abstract:
An agricultural implement system is provided that includes a down force cylinder configured to apply a downward force to a row unit, a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit, a press wheel cylinder configured to vary contact force between a press wheel and a soil surface, a closing disk cylinder configured to vary contact force between a closing disk and the soil surface, a residue manager cylinder configured to vary contact force between a residue manager and the soil surface, or a combination thereof. The agricultural implement system also includes an electronic control unit configured to automatically regulate a pressure within the cylinders, and a manual backup system configured to facilitate manual pressure adjustment of the cylinders.
