DEFINITION

Classification: 172/118

(under subclass 35) Apparatus in which an earth working element is driven about an axis which is parallel to the ground or disposed at an angle relative to the ground and is additionally located in a plane which is transverse to the direction of travel of the earth working element.

(1) Note. This subclass includes those earth working elements which are driven to and fro in an arcuate path about an axis extending transversely to the direction of draft; e.g., oscillating hoes and choppers.

SEE OR SEARCH THIS CLASS, SUBCLASS:

61+, for earth working elements which are intermittently driven back and forth in an oscillatory path about an axis that is disposed transversely to the direction.

124, for earth working elements which are disposed at an angle other than 90 deg. to the direction of draft as viewed in plan.
