Total Claims: 10
Claim 1
Independent Claim
278 words
A method of cutting grass and bagging the cut portions of the grass with a lawn mower having a housing enclosing a chamber, said housing including a top wall having front and rear portions and a continuous downwardly directed imperforate side wall extending entirely around the periphery of said top wall, motor means mounted generally centrally of said top wall, cutter blade means drivably connected to the motor means and located in the chamber below the top wall for rotation about a vertical axis, said cutter blade means having lift portions for causing air and cut grass to move vertically upwardly, said front portion of the top wall having an arcuate material discharge opening and a bagging chute for carrying the material from the opening upwardly and rearwardly over the motor means, to a material collection bag comprising: moving the lawn mower in a direction to locate grass in the front area of the chamber, behind the side wall, erecting the grass in the front area of the chamber by moving air upwardly through the grass in the front area of the chamber, by rotating the cutter blade means about a vertical axis whereby the lift portions cause air to move under the side wall and vertically upwardly through the arcuate material discharge chute, cutting off top portions of the erected grass with the rotating cutter blade means, moving the cut portions of the grass vertically upwardly through the discharge opening, with the moving air caused by rotating the cutter blade means and delivering the cut portions of the grass through the bagging chute from the discharge opening upwardly and rearwardly over the motor means to the bag.
Claim 2
Independent Claim
278 words
A method of cutting grass and bagging the cut portions of the grass with a lawn mower having a housing enclosing a chamber, said housing including a top wall having front and rear portions and a continuous downwardly directed imperforate side wall extending entirely around the periphery of said top wall, motor means mounted generally centrally of said top wall, cutter blade means drivably connected to the motor means and located in the chamber below the top wall for rotation about a vertical axis, said cutter blade means having lift portions for causing air and cut grass to move vertically upwardly, said front portion of the top wall having an arcuate material discharge opening and a bagging chute for carrying the material from the opening upwardly and rearwardly over the motor means, to a material collection bag comprising: moving the lawn mower in a direction to locate grass in the front area of the chamber, behind the side wall, erecting the grass in the front area of the chamber by moving air upwardly through the grass in the front area of the chamber, by rotating the cutter blade means about a vertical axis whereby the lift portions cause air to move under the side wall and vertically upwardly through the arcuate material discharge chute, cutting off top portions of the erected grass with the rotating cutter blade means, moving the cut portions of the grass vertically upwardly through the discharge opening, with the moving air caused by rotating the cutter blade means and delivering the cut portions of the grass through the bagging chute from the discharge opening upwardly and rearwardly over the motor means to the bag.
