ABSTRACT:
A tillage machine includes a main frame that supports rotary soil working tined members and various additional tools that can be detachably fastened to the main frame in combination with the rotary tined members to landscape in one pass. For primary use, a ripper assembly is detachably fastened at the front of the frame in advance of the rotary soil working members. A pulverizer-support roller is detachably fastened to the frame in a trailing position and a leveler bar supported between the roller and the rotary members to prevent ridging. A seed box with delivery system can be mounted on the roller frame and driven by a transmission connected to the roller axle. A packer roller is detachably pivoted to the frame to leave the ground in a finished condition.
