Abstract: A mower comprising a frame, a deck with a discharge located forwardly of at least one cutting blade, a baffle in the deck disposed between the blade and discharge that is spaced from the top wall of the deck defining a discharge aperture in the deck that creates suction and focuses clippings toward the discharge, and wheels coupled to the frame by a suspension preferably of independent construction. Each blade is massive for high inertia, generally planar, and disc-shaped having at least three cutting arms that each have a tab extending below the plane and having a cutting edge. Each arm preferably also has an upwardly extending suction-increasing flap. The suspension has a pair of control arms pivotally mounted to the frame with each arm having a mounting arm extending above the frame capturing a biasing element that urges the arms away from each other to keep the wheels in contact with the ground.
