DEFINITION

Classification: 172/662

(under subclass 613) Apparatus in which the earth working elements are mounted on a supporting frame and one or more of said elements are so related thereto as to be capable of movement from an earth working position to a rest position, for example, to change the spacing between adjacent elements or to enable transport of the frame over the earth.

(1) Note. Since almost any vertical adjustment may be continued far enough to result in a movement to transport position this definition is limited to those devices in which some means is shown for adjusting or holding the element in transport position other than a mere vertical-adjusting means such as is intended to adjust the vertical working position of the tool in the ground.
