Abstract text

An improved hand held lawn and garden vacuum trimmer having an elongated vacuum duct in fluid communication with a motor powered vacuum impeller positioned in a body, one end of the vacuum duct being attached to the body, a rotary cutter positioned in the vacuum duct, the rotary cutter attached to the impeller by way of a rotating shaft so that material swept into the distal end of the vacuum duct is cut by the cutter, swept through the impeller and then directed to a collection container. The improvement of this embodiment of the instant invention is positioning the cutter more than one quarter inch and less than three inches from the distal end of the vacuum duct.

In addition, an improved hand held lawn and garden vacuum collector having an elongated vacuum duct in fluid communication with a motor powered vacuum impeller positioned in a body, one end of the vacuum duct being attached to the body, so that material swept into the distal end of the vacuum duct is swept through the impeller and then directed to a collection container, wherein the improvement of this embodiment of the instant invention is to position a rotary cutter and airfoil in the vacuum duct, the rotary cutter connected to the airfoil so that the rotary cutter rotates in response to air flowed through the vacuum duct.

And, a vacuum duct assembly adapted to be removeably attached to a hand held lawn and garden vacuum collector, the hand held lawn and garden vacuum collector having a motor powered vacuum impeller encased in a body. The vacuum duct assembly consists of an elongated vacuum duct having means for demountable attachment at the first end thereof to the body of the collector, a rotary cutter positioned in the vacuum duct more than one quarter inch and less than three inches from the second end of the vacuum duct, the rotary cutter attached to one end of a shaft positioned in the vacuum duct, the other end of the shaft having means for attachment to the vacuum impeller when the first end of the vacuum duct is attached to the body of the collector.
