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. The deck is pivotally mounted to an arm that is pivotally mounted to the frame and urged upwardly by a torsion spring or the like such that it floats along the ground. The mower preferably is of rear wheel drive construction with the suspension coupling front wheels to the frame. The combination of these elements results in a mower capable of high quality cutting under a variety of cutting conditions over diverse terrain while minimizing scalping and power input.

[ What is claimed is:] [1.] A mower comprising:a) a frame;b) a plurality of wheels carried by the frame with at least one of the wheels disposed adjacent a front end of the mower and in contact with the ground and at least one of the wheels disposed adjacent a rear end of the mower and in contact with the ground;c) a cutting deck carried by the frame;d) a cutting blade housed within the deck, the cutting blade having a diameter and a generally disc-shaped body that is disposed generally in a plane when it is rotated, the disc-shaped body comprising an upper surface, a lower surface disposed toward the ground, and at least three circumferentially spaced apart cutting arms that extend radially outwardly from the disc-shaped body, each of the cutting arms comprising a leading edge with a cutting tab that extends downwardly at an angle relative to the plane and that is defined by a radial bend line and a trailing edge with a flap that extends upwardly at an angle relative to the plane, and each cutting tab comprising a cutting edge disposed along an edge of the cutting tab disposed adjacent the ground, wherein the cutting blade has a weight of at least one pound and eight ounces and has a weight-to-diameter ratio of between about 2.0 ounces per inch of diameter and about 4.5 ounces per inch of diameter, and wherein, during operation, the cutting blade is turned at a rotational speed of at least about 3,500 revolutions per minute and no greater than about 5,000 revolutions per minute such that the velocity of the radial periphery of the cutting blade is at least about 14,000 feet per minute and no greater than about 19,000 feet per minute; ande) a prime mover carried by the frame and operably coupled to the blade for rotating the blade.
