A device for processing the soil having a frame which carries at least one processing tool and a resilient element which has a first end portion which is associated with the processing tool and a second end portion which is associated with the frame by connection devices. The connection devices have a first laminar element which is arranged in an upper position with respect to the second end portion of the resilient element and a second laminar element which is arranged in a lower position with respect to the second end portion. The connection devices further include a separator device arranged between the first laminar element and the second laminar element which is capable of forming a separation between the second end portion and the laminar elements which defines a cavity between the first laminar element and the second laminar element, inside which the resilient element can bend.

An agricultural row unit includes a linkage assembly that is pivotably coupled to an attachment frame. A hydraulic cylinder is coupled to the linkage assembly and applies pressure to the linkage assembly. A controller is mounted in the row unit such that is coupled to the hydraulic cylinder for controlling the pressure applied by the hydraulic cylinder.
