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. 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.
