Abstract: The present disclosure relates to a robotic lawnmower cutting deck (130) comprising a cutting system (131) which in turn comprises at least two cutters (132a, 132b, 132c), with a cutting disc (133a, 133b, 133c) and cutter motor (134a, 134b, 134c). The cutters (132a, 132b, 132c) are supported by a cutter support beam (135) which has a longitudinal beam extension (L1) and in turn is supported at respective supporting positions (135a, 135b) by a corresponding first link arm (136a, 136b) and a corresponding second link arm (137a, 137b).

Abstract: A chainsaw cutting link (1b) comprises a cutting tooth (7b) with a side plate (12b) and a top plate (10b), defining an L-shaped cutting edge (13b, 14b). The top plate (10b) comprises an outer surface (11b) with a first outer surface portion and a depressed second outer surface portion (16). A saw chain comprises a plurality of such cutting links (1b). Use of such cutting links (1b) or such a saw chain increases the ability of making bore cuts. A method of manufacturing a cutting link (1b) comprises: punching a piece of material to form a cutting link (1b) blank with a top plate portion (10b) and a side plate portion (12b); bending the top plate portion (10b) to form an L-shaped cutting edge (13b, 14b); and grinding thereof. An area of the top plate (10b), corresponding to the second outer surface (16) is depressed.
