Abstract: The present invention entails a plant clipping system for clipping the top portion of growing plants. A boom structure is supported over an area of underlying plants. A plant clipping device is movably mounted on the boom structure and depends downwardly therefrom. In operation, the plant clipping device is fixed in a certain position on the boom structure and the boom is moved over the underlying plants and during this process the plant clipping device clips the top portion of the plants. The plant clipping device can be laterally adjusted on the boom structure such that it can be moved from one location to another location on the boom structure. By repeatedly shifting the position of the plant clipping device on the boom structure after each boom traverse it is seen that a relatively large area of plants underlying the boom structure can be clipped.

Abstract: This invention is an irrigation system which is mounted on parallel tracks and spans the distance therebetween. The main frame is of the truss type and includes a drive means on each end thereof. Also, a tensioning means is provided to assure perpendicular travel of the irrigation system relative to the support track to prevent any twisting tendency. The system can be operated either automatically or manually, and when on automatic, it will cycle back and forth over the designated area.
