Abstract: The present invention relates to a cultivator having a frame which includes at last one line of hinges with axes transversely disposed to the direction of draft of the cultivator. The portion of the cultivator frame ahead of the front row of hinges is known as the leading tool-carrying frame and carries a row of shanks with cultivator shovels disposed abreast along the length of the leading tool-carrying frame. One or more additional rows of hinges with axes transversely disposed to the direction of draft can be provided in the cultivator frame to the rear of the front row of hinges. The frame-work depending upon and following behind a given row of hinges is known as a following tool-carrying frame. Each following tool-carrying frame also carries a row of cultivator shanks. The provision of each of these rows of hinges with axes transversely to the direction of draft provides an additional degree of freedom for the cultivator frame to conform to knolls or depressions in an agricultural field.
