Abstract
An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.
Claims8
An agricultural implement system, comprising:
- 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 down force control valve in fluid communication with the down force cylinder, wherein the down force control valve is configured to regulate a flow of fluid to the down force cylinder to adjust the downward force;
- and
- a down force control cylinder coupled to the down force control valve and in fluid communication with the depth control cylinder, wherein the down force control cylinder is configured to vary fluid pressure within the down force cylinder by adjusting the flow of fluid through the down force control valve based on fluid pressure within the depth control cylinder.
