ABSTRACT:
A lawn mower includes a housing, and two cutter members rotatably attached to the housing and rotated relative to each other in a reciprocating action, such that the cutter members may be actuated as a shearing action for cutting and trimming purposes. The cutter members are not required to be rotated in a high speed such that the grass cut by the cutter members will not fly out in a fast speed. Two followers are secured to the cutter members respectively, and two cams are engaged with the followers for rotating the followers and thus the cutter members in the reciprocation action relative to each other for forming the shearing action.
