DEFINITION

Classification: 171/103

(under subclass 84) Apparatus in which the separating digger includes two mutually cooperating digger surfaces which extend, side by side, downwardly in the direction of draft and which are spaced apart at a distance such that said surfaces are adapted to contact opposite sides of each object being recovered to lift said object and guide it along said surfaces.

(1) Note. The cooperating surfaces may be formed as part of an integral unit provided that there is an adequate opening or clear space below and between said surfaces to allow soil to pass through freely as the object is lifted therefrom.

(2) Note. The surfaces are usualy flat and disposed in upwardly and laterally diverging planes but they may be surfaces of rods or bars.

SEE OR SEARCH THIS CLASS, SUBCLASS:

57, and 58, for spaced, downwardly inclined, rotating members which engage opposite sides of a plant to extract it from the ground and which may enter the earth at their forward ends to form spaced digging means.

62, for plant- or buried-object extractors combined with diggers or root cutters which may be formed as pairs of inclined shares or guides. 104+, for devices which are disclosed as having closely spaced digger elements which form an interstitial supporting surface upon which the objects being recovered rest but in which spaced elements do not contact opposite sides of said objects.
