A rotary lawn mower characterized by an elongated framework presenting a rear power portion and rotor-cutter blade assemblies rotatable around wheel supported shafts connecting to said framework at the front thereof and featuring a cutter blade vertical adjustment operable in unison by a chain-sprocket arrangement for achieving uniform cutting. Vertical displacement of the rotor-cutter blade assemblies is accomplished by rotation of threaded members secured to decking overlying the rotor-cutter blade assemblies and vertically movable therewith. A power source serves to drive the wheels for the power portion of the mower and, as well, the front cutter portion, i.e. the rotor-cutter blade assemblies.
