Abstract

A conservation tillage tool, including a main frame and a rear frame pivotally mounted on the main frame disposed to support a number of soil working implements in sequence. The main frame is supported by ground wheels attached to the rear section of the main frame. The wheels are movable with respect to the main frame to move the latter between a raised transport position and a number of lowered working positions. A tongue and hitch unit connect the main frame to a prime mover, and a leveling mechanism operably interconnects the main frame, ground wheels and tongue for maintaining the main frame level at any of its positions. A spring-cushioned linkage operably interconnects one of the implements at the front of the main frame with one of the implements mounted on the rear frame for simultaneously raising and lowering those two implements between transport and working positions. A suspension linkage operates in concert with the spring-cushioned linkage for permitting the rear implement to raise according to terrain independent of the front implement.
