A mower comprising an edge guide located adjacent an outer surface of a side wall and at least partially surrounding an opening. The edge guide comprises an inlet and is arranged to guide vegetation towards the opening. The edge guide defines a channel having at least one direction change between the inlet and the opening such that there is no line of sight between the inlet and the cutter element. By providing an edge guide having a convoluted path or channel, an opening in the side wall of the cutter housing can extend vertically up to the plane of the cutter element while still providing a 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.
