Abstract:
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.

Claim (Index 16):
An implement apparatus comprising:\n a tool bar frame mounted on tool bar wheels for travel along a ground surface in an operating travel direction; a tool carrier assembly comprising a carrier frame and a plurality of ground engaging tools mounted thereon; a carrier control assembly comprising a crank arm pivotally attached to a rear portion of the tool bar frame about a crank axis oriented substantially horizontally and perpendicular to the operating travel direction, and an extendable hydraulic cylinder attached between the crank arm and the tool bar frame and operative to pivot the crank arm about the crank axis; wherein the carrier frame is pivotally attached at a front end thereof to the crank arm about a carrier axis oriented substantially parallel to the crank axis; wherein the carrier control assembly is configured such that when the hydraulic cylinder is in an extended position the tool carrier assembly is in a transport orientation extending upward from the tool bar frame, and such that retracting the hydraulic cylinder to a first retracted position moves the tool carrier assembly to an operating orientation extending substantially horizontally rearward from the tool bar frame; wherein the carrier control assembly is configured such that the tool carrier assembly is maintained in the operating orientation when the hydraulic cylinder is further retracted from the first retracted position to move the tool carrier assembly from a headland position, where the ground engaging tools are above the ground, down to a working position where the ground engaging tools penetrate the ground surface; and wherein the carrier control assembly is configured such that when the tool carrier assembly is in the working position, pressurized hydraulic fluid is directed into the hydraulic cylinder such that the hydraulic cylinder exerts a downward bias force on the tool carrier assembly and such that hydraulic fluid moves in and out of the hydraulic cylinder as the tool carrier assembly moves up and down and the hydraulic cylinder extends and retracts in response to elevation changes in the ground surface.
