ABSTRACT:
A lawn mower has a transverse cutting bar, but instead of a reel-type cutter to cooperate therewith, a rotary cutter is employed that has a plurality of curved cutting edges that maintain constant contact with the transverse cutting bar and repeatedly traverse the cutting bar with the cutting bar positioned more or less tangentially of the curved cutting edges. In all embodiments of the invention, the cutting edges are substantially circular and concentric as viewed along the axis of the rotary cutter, and in at least most embodiments the rotating cutting edges eliminate hazard to the operator by pushing away out of harm any part of the operator's body that may inadvertently intrude into the zone of the cutting operation. In the presently preferred embodiment, the cutting edges are the peripheral edges of a plurality of spaced discs that are inclined to wobble along the transverse cutting bar. Each disc reciprocates along a portion of the length of the transverse cutting bar with the ranges of reciprocation overlapping to result in a smooth cutting swath. Arrays of resilient filaments may be mounted on the rotary cutter to encounter the transverse cutting bar and thus flick loose material into a blower for conveyance away from the cutting zone. A pivoted device to sharpen the cutting edges may be temporarily mounted on the mower frame.
