DEFINITION

Classification: 172/13

(under the class definition) Apparatus comprising means other than a scraper specially intended for working the earth adjacent a fixed structure on the surface of the earth (e.g., a paved walk to edge a lawn) or working the earth adjacent a turf surface (e.g., grooving a plant bed adjacent a lawn).

(1) Note. This definition is intended to provide an art collection of lawn edgers or trimmers. Usually such devices comprise a means for guiding the device along the edge of the pavement. However no special structure need be claimed for classification in this subclass. Patents whose sole specific disclosure or whose claims relate to the described use are considered to come under this definition.

30, Cutlery, appropriate subclasses for hand manipulable implements for merely cutting or slitting grass or sod. Devices which cut so as to form a groove in the soil, however, are classified in Class 172.

56, Harvesters,

10.1+, for a motor-driven harvester, particularly subclass 13.7, wherein two or more cutters are provided, e.g., for mowing and for trimming, and subclass 16.9 wherein the motor may drive a mower or a trimmer; subclasses 229+, for a lawn and hedge cutter, and subclass 251, for a lawn edge trimmer combined with a lawn mower. The lawn edge trimmer or cutter of Class 56 merely cuts grass. If a groove is cut in the soil, or the ground is otherwise disturbed, classification is in an appropriate subclass in Class 172.
