摘要： An implement has right and left pivotally attached tool bar frames movable from an operating position extending laterally to a transport position extending forward from the connecting pivot axis. Right and left hitch arms are pivotally attached about vertical axes at rear ends to spaced apart locations the right and left tool bar frames and extend forward and inward when the tool bar frame is in the operating position. A hitch frame is pivotally attached at right and left rear portions thereof to front ends of the hitch arms about vertical axes. When the tool bar frame is in the transport position, the rear end of the hitch frame is forward of the right and left tool bar frames, and the front end of the hitch frame, attachable to a tractor, is a desired clearance distance forward of the right and left tool bar frames.

摘要： A tool carrier has a carrier frame and ground tools, and a front end of the carrier frame is connected to a wheel supported tool bar frame. A crank arm is pivotally attached to the tool bar frame about a crank axis oriented horizontally and perpendicular to an operating direction. A front end of the carrier frame is pivotally attached to the crank arm about a carrier axis parallel to the crank axis, and a hydraulic cylinder attached between the crank arm and the tool bar moves the tool carrier from an upward transport orientation to a rearward extending horizontal operating orientation, and maintains the tool carrier horizontal while moving it from a headland position above the ground to a working position where the tools penetrate the ground. When the tool carrier assembly is in the working position, the hydraulic cylinder exerts a downward bias force on the tool carrier.
