Disclosed herein is a rotary lawn mower comprising a blade housing supported for travel in adjacent relation to the ground, a first rotary cutter blade supported for rotation within the blade housing, a second rotary cutter blade supported for rotation within the housing about an axis located in laterally rearwardly offset relation from the rotary axis of the first cutter blade and for clipping discharge from the rotary path of the second cutter blade into the rotary path of the first cutter blade, and a grass clipping discharge arranged for delivery thereto of clippings solely from the rotary path of the first cutter blade.
Claims24
A rotary lawn mower comprising a blade housing, means supporting said blade housing for travel in a forward direction in adjacent relation to the ground, a first rotary cutter blade supported for rotation within said blade housing about a forwardly located axis, and a second rotary cutter blade supported for rotation within said blade housing about an axis located in laterally rearwardly offset relation from said rotary axis of said forwardly located first cutter blade, said blade housing further including a grass clipping discharge outlet located, at least in part, forwardly of said rotary axis of said forwardly located first cutter blade, and diametrically opposite with respect to said rotary axis of said forwardly located first cutter blade from said rotary axis of said rearwardly located second cutter blade, and in adjacent relation to the rotary path of said forwardly located first cutter blade for discharging from said blade housing grass clippings delivered solely from said forwardly located first cutter blade, said blade housing further including a depending wall including a generally straight portion extending in adjacent relation to a tangent extending from the peripheries of the rotary paths of said cutter blades, a first arcuate portion merging with said straight portion and extending in the direction counter to the direction of rotation of said rearwardly located second cutter blade, whereby the grass clippings cut by said rearwardly located second cutter blade are delivered to the path of the forwardly located first cutter blade adjacent to said depending wall straight portion, and a second arcuate portion extending in adjacent relation to the rotary path of said forwardly located first cutter blade from said first arcuate portion in the direction counter to the direction of rotation of said forwardly located first cutter blade, whereby the grass clippings cut by said forwardly located first cutter blade and the grass clippings delivered to the path of the forwardly located first cutter blade from the rearwardly located second cutter blade are delivered from said blade housing through said discharge outlet.
A rotary lawn mower comprising a blade housing, means supporting said blade housing for travel in a forward direction in adjacent relation to the ground, a first rotary cutter blade supported for rotation within said blade housing about a forwardly located axis, and a second rotary cutter blade supported for rotation within said blade housing about an axis located in laterally rearwardly offset relation from said rotary axis of said forwardly located first cutter blade, said blade housing further including a grass clipping discharge outlet located, at least in part, forwardly of said rotary axis of said forwardly located first cutter blade, and diametrically opposite with respect to said rotary axis of said forwardly located first cutter blade from said rotary axis of said rearwardly located second cutter blade, and in adjacent relation to the rotary path of said forwardly located first cutter blade for discharging from said blade housing grass clippings delivered solely from said forwardly located first cutter blade, said blade housing further including a depending wall including a generally straight portion extending in adjacent relation to a tangent extending from the peripheries of the rotary paths of said cutter blades, said depending wall further including an arcuate portion in adjacent relation to a rearward part of the periphery of the rotary path of at least one of said cutter blades, means for rotating said second cutter blade in the direction which is effective to discharge grass clippings forwardly along said straight portion of said depending wall and into the path of rotation of said second cutter blade, whereby the grass clippings cut by said rearwardly located second cutter blade are delivered to the path of the forwardly located first cutter blade adjacent to said depending wall straight portion, and means for rotating said second cutter blade in the same rotary direction as said first cutter blade, whereby the grass clippings cut by said forwardly located first cutter blade and the grass clippings delivered to the path of the forwardly located first cutter blade from the rearwardly located second cutter blade are delivered from said blade housing through said discharge outlet.
