DEFINITION

Classification: 172/297

(under the class definition) Apparatus comprising an earth working element which is entirely located in front of the rearmost point of the frame or wheels of a self-propelled vehicle.

(1) Note. Patents having a sole specific disclosure of an earth working element forward of the rear of a self-propelled vehicle are classified under this definition even if the location is not claimed, provided that some reference to the vehicle is made in the claims. The reference to the vehicle may be no more than a reference to a frame disclosed as rigidly attached to the vehicle.

(2) Note. The rearmost point is determined by the direction of movement of the vehicle when in use, the earth working element being ahead of the rear in the direction of movement.
