ABSTRACT:
A system for actuating a plurality of farm implements includes a frame adapted to be connected between a tractor and a first farm implement such as a drill. A tool frame, adapted to be connected to one or more additional farm implements, is pivotally suspended beneath the frame by front and rear support linkages. The rear support linkages are also connected with a linkage which raises and lowers the grain drills on the drill. An hydraulic actuator is connected to the front support linkage to move the tool frame and the drill between a transport position and a working position. Adjustment means are provided at the connection between the rear support linkage and the linkage to the drill for determining the transport height of the drill, the spring tension on the grain drills, and the height of the rear of the tool frame with respect to the front of the tool frame.
