  • Patent number: 8756905
    Abstract: 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.

  • Publication number: 20080256805
    Abstract: The present invention provides a power tool comprising: at least a pair of handles (10, 20), wherein each of the pair of handles has (a) a respective actuator (14, 24) for operating said power tool; and (b) a respective guard member (16, 26) for restricting access to said respective actuator; the power tool further comprising a latch mechanism (72, 74) for latching the pair of handles (10, 20) together, wherein the latch mechanism has a first component (72) mounted on a first one (16) of said guard members and a second component (74) mounted on a second one (26) of said guard members and adapted to engage with said first component (72). Thus, the components of the latch mechanism are mounted on the respective guard members for the actuators, rather than directly on the handles themselves. This ensures that the components of the latch mechanism are able to latch the handles together without being impeded by the presence of the guard members or the actuators.
