A robotic work tool system () for defining a working area () in which a robotic work tool () is subsequently intended to operate. The robotic work tool system () comprises a robotic work tool (), at least one controller () and at least one memory (). The robotic work tool () comprises at least one sensor unit () configured to collect sensed input data while the robotic work tool () is driven around the working area () to preliminarily define a perimeter around the working area (). The at least one controller () is configured to establish a preliminary working area perimeter (). The at least one memory () is configured to store a perimeter adjustment function and instructions that cause the at least one controller () to adjust the perimeter of the working area () by applying the stored perimeter adjustment function to the established preliminary working area perimeter () and thereby produce an adjusted working area perimeter (). The perimeter adjustment function is based on the collected sensed input data corresponding to terrain features.

The present disclosure relates to a lawnmower for processing lawn surface. The lawn mower comprises a chassis, at least partially carried by a set of wheels adapted to rest on the lawn surface, and one or more cutting devices suspended by the chassis. An outer cover, enclosing the chassis and is open towards the lawn surface to form an enclosed space between the outer cover and the lawn surface. A divider plate divides the enclosed space into an upper space and a cutting space, the divider plate generally extending along a plane that is approximately parallel with the lawn surface. The cutting device projects through an opening in the divider plate and edges of the divider plate are connected to the outer cover.
