There is provided a mower (100) comprising a cutter housing (116) arranged to enclose partially a cutter element (110) having a cutting plane (P). The cutter housing (116) comprises a side wall (118) which extends below the cutting plane (P), the side wall (118) having an opening (130) formed therein which extends from a base of the side wall (118) to at least the level of the cutting plane (P). The mower (100) further comprises at least one edge guide (120) located adjacent an outer surface of the side wall (118) and at least partially surrounding the opening (130). The edge guide (120) comprises an inlet (126) and is arranged, in use, to guide vegetation towards the opening (130). The edge guide (120) defines a channel (128) having at least one direction change between the inlet (126) and the opening (130) such that, in use, there is no line of sight between the inlet (130) and the cutter element (110). By providing an edge guide having a convoluted path or channel, an opening in the side wall of the cutter housing can be provided which extends vertically up to (or beyond) the plane of the cutter element (such as a blade) whilst still providing a fully radially-enclosed cutter element as required by safety regulations. Therefore, edge-located vegetation can be fed to the cutter in a more upright configuration for improved cutting.
