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.2/9 1 FIG. 2 9 DBF 15 9 35 9 31 13 33 , oO g21 o oo 7 25 3 5L 17 51 19 FIG. 3A 29-- 35A 3BDBF CAX CRX3 31 CBE HFX 33 oO g 21 27 7 253 WLX 19 HRX FIG. 3A 41 3 43 $] CRX ROX . o.' . o.39 CA 37
