(under subclass 518) Apparatus comprising a plurality of earth working element, handled as a unit, which unit is adapted to be turned to positions 180 deg. apart from each other in plan view, for use in earth working in either position (e.g., to throw the earth either to the right or left).
(1) Note. Many disk gangs are inherently reversible. For classification under this definition a claim must make specific reference to the reversible feature.
SEE OR SEARCH THIS CLASS, SUBCLASS:
219+, for a group of rolling earth working elements movable to reversed position by an actuating means comprising more than a mere handle rigidly attached to the frame to be moved.
254, for devices which are changeable in function due to rearrangement of earth working elements, but not including devices as defined in subclass 577.
702+, for an earth working apparatus having a reversible port other than a disk gang.
