  • Folding flexible undercutter plow
    Patent number: 4206816
    Abstract: Apparatus is disclosed for folding an articulated agricultural implement such as a multisection plow in order to facilitate movement of the implement from field to field along available roadways. Stability in the folded condition and minimization of the number of hydraulic cylinders required are achieved through the use of a gravity operated lock arrangement associated with adjacent sections of the foldable wing frame units of the implement. The number of locks and hydraulic cylinders depends upon the total number of hinged sections used to form the base and wing units of the frame assembly. The inboard hydraulic cylinders are pivotally connected to respective draft beams on the base unit and each acts directly between such beam and the associated wing unit.
    Type: Grant
    Filed: October 27, 1978
    Date of Patent: June 10, 1980
    Assignee: Richardson Manufacturing Company, Inc.
    Inventors: Raymond W. Richardson, Robert E. Burda, John C. Crumrine
