DEFINITION

Classification: 171/77

(under subclass 71) Apparatus which includes in addition to a separator having an intersitial separating surface movably mounted in a position adjoining a plow member, a separator supporting member of irregular or eccentric shape interposed between the separator and the ground in such fashion that the supporting member is turned about an axis by contact with the ground and imparts a motion to the separator in response to such turning.

(1) Note. The noncircular rolling member may be supported on the separator itself, on a supporting frame carrying the separator, or on a separate frame or subframe provided especially for the rolling member.
