(under subclass 35) Apparatus in which a tooth, tine or like earth working part is so freely pivotally mounted on a driven rotary carrier that during carrier rotation centrifugal forces cause the free end of said tooth, tine, or like to swing to a radial position relative to the axis of rotation of such carrier.

(1) Note. This definition includes teeth or tines which are freely pivotally connected to a rotary carrier by means of a flexible chain.
