Abstract: A simplified, low component harrow attachment includes several clevis-like mounting castings pivotally connected between two identical flat side sheets. A link which pivots the ranks in unison is pinned to the legs of the mounting castings between the sheets by free-floating pins captured between the sheets. The castings can pivot to a retracted position and be secured by a pin for increased clearance between the teeth and the ground during transport. The rear mounting casting has a longer clevis structure than the remainder of the castings and serves as a tine depth stop when a stop pin is inserted through apertures in the sheets.
Abstract: A disc gang is provided that is suitable for use as part of a multifunctional seedbed preparation implement or in a standalone disc harrow. The disc gang is configured to permit a gang angle of the disc gang to be adjusted to accommodate differing soil conditions and/or to obtain different tillage characteristics. The disc gang may include a frame mounted on a mainframe of a primary tillage implement such as a cultivator. The frame includes a main beam mounted on the implement's mainframe and a disc support beam connected to the main beam and supporting a plurality of rotating discs. The gang angle can be infinitely adjusted through a designated range by pivoting one end of the disc gang about a vertical pivot axis while permitting another end portion of the disc gang to slide along a support surface for that end.
Abstract: An implement having a frame adapted to be transported in earth traversing movement along a predetermined path of travel; a first earth working tool mounted on the frame disposed for engagement with the earth during such earth traversing movement and operable to move earth laterally of the path of travel; a second earth working tool mounted on the frame forwardly of the first earth working tool relative to the path of travel disposed for engagement with the earth during the earth traversing movement and operable to move earth laterally of the path of travel; and a third earth working tool mounted on the frame rearwardly of the first earth working tool relative to the path of travel and disposed for engagement with the earth during such earth traversing movement and operable to move earth laterally of the path of travel and wherein the directions of movement of the earth laterally of the path of travel by the first, second and third earth working tools is such as to work the earth substantially evenly and to re
