ABSTRACT:
A ground working implement is disclosed which comprises three rectangular frames connected together by means of hinges. A center frame is provided with a tongue for attachment to a traction device such as a tractor. Each of the frames is provided with a packer wheel attached to and extending along the rear portion thereof and each of the frames is also provided with a separate frame from which S tines depend. S tines are sometimes referred to as Danish tines. The separate frames are connected to the first frame by means of a bell crank which is fulcrumed on members depending from the first frame and which are connected together by means of levers which in turn are connected to a rotatable shaft. Each frame is provided with a rotatable shaft which are connected together for concurrent rotation by an articulated connection permitting the outermost frames to be rotated 180.degree. by means of hydraulic cylinders and supported on the center frame for road transportation. A hydraulic cylinder is provided in the center frame which rotates the shaft on that frame to raise or lower the wheels used for road transportation. Lowering the wheels lifts both the packer wheels and the tines up to a safe distance above the ground level and brings the second frame closer to the first frame. The reverse of this movement of the hydraulic cylinder causes the wheels to raise and the packer wheels to rest on the ground. Further movement of the hydraulic cylinder determines the degree of vertical penetration into the ground on the part of the tines.
