ABSTRACT:
A light soil tillage implement is adapted to be drawn by a farm tractor, and is designed to perform a light tillage immediately preceeding fertilizing, planting, and/or other farming operations. The implement comprises a frame having support wheels thereon engaging the ground, one or more tool bars having ground working tools thereon, and a mounting mechanism for each tool bar connecting each tool bar with the frame. Each mounting mechanism comprises a series of linkage elements which resiliently bias the working tools downwardly into the soil when the implement is in a tilling position. The mounting mechanism is adapted to positively lift the tools and tool bars out of engagement with the ground when it is desired to transport the implement, and further individually mounts each tool bar in a manner which allows the same to laterally rotate about a central point thereon in order to follow the contour of the soil independent from the other tool bars. Additional equipment for the farming operations is connected to the tillage implement by a hitching mechanism to allow lateral rotation thereof with respect to the tillage implement, and allow the tillage implement to be used in tandem with trailing farming operations on uneven ground.
