DEFINITION

Classification: 172/50

(under subclass 48) Apparatus which include a plurality of driven earth working elements which are not identical.

(1) Note. Differences in size or shape constitute matter for this definition but mere differences in rotary displacement (phase), position or attitude are excluded and are classified in a pertinent subclass herebelow on the basis of the features of each individual earth working element. For example, mirror images are not considered to be differences of shape.
