A multiblade lawn mower including a mower deck having a plurality of cutting blades rotatably disposed therein. A first flow control baffle is positioned in the mower deck between the cutting blades and the front wall of the mower deck and extends substantially continuously between the sides of the mower deck. A second flow control baffle is positioned in the mower deck rearwardly of the cutting blades. The first and second flow control baffles include a plurality of semi-circular baffle portions which define a plurality of open throat portions therebetween. A plurality of selectively removable mulcher baffles are positioned in the mower deck to close the throat portions, thereby defining a substantially cylindrical mulching chamber around each of the cutting blades.
