发明名称 Soil cultivating implements
摘要 A soil cultivating implement is structured to work soil across a broad path and includes a frame that can be towed when hitched to trail substantially behind the rear of a prime mover. The main frame supports a central frame portion and an outer frame portion is pivoted at each lateral end of the central portion. Each frame portion is elongated with a corresponding group of soil working members being rotatably mounted on upwardly extending axes. The frame portions and groups of soil working members are located side-by-side in a row that extends transverse to the direction of operative travel. For transport purposes, each outer group is pivoted by a hydraulic system to an upwardly tilted position to narrow the implement's width. Ground wheels are hydraulically interconnected to the frame and positioned at the rear of the central portion to sustain essentially all of the implement's weight. The height of the implement frame is adjustable with the wheels. Each outer portion is pivoted to the central portion and interconnected to a transverse beam of the frame by a forward pivot connection. A planting implement, such as a seed drill is attachable to the frame at the rear of the wheels and the seed drill frame is also foldable to a narrow transport position.
