Abstract
An agricultural implement and attachment are described for soil conditioning. The implement may include an implement frame, with the attachment configured to be towed by the implement frame. A pressurized fluid circuit may be configured to control one or more actuators, in order to provide lifting or lowering force to the attachment. The attachment may include a leading frame and a trailing frame, each configured to support a set of agricultural tools. The trailing frame may be mounted to the implement frame via the leading frame.
