摘要： A method of removing debris from an area of turf grass can include providing a grass treatment system including a comb having a leading edge comprising a plurality of comb teeth, wherein the comb is mounted transversely to a direction of travel, and a substantially cylindrical brush positioned above the comb and configured to engage at least a portion of a top surface of the comb, wherein the brush rotates relative to the comb. The method can include positioning the grass treatment system closely adjacent to the turf grass such that the comb engages debris on and around the turf grass surface, and moving the grass treatment so that (i) the comb engages the debris, (ii) the rotating brush removes at least a portion of the debris from the surface of the comb, and (iii) the rotating brush does not come into contact with the turf grass.

摘要： The present invention is directed to a debris collection bag for a blowervac device that is carried on a user's back. This improves the user's mobility and allows an increased capacity for the collection bag. The bag's location provides a comfortable weight distribution by separating the weight of the blowervac from the weight of the collection bag. The bag has a dust dispersion system to direct dust away from the user. The bag has a closure located on the side which makes emptying the bag easier. The bag closure is provided to make opening and closing the bag easier and faster, and resistant to dust and debris.

摘要： A leaf collection assembly for collecting leaves falling from a tree includes a collar that is positionable around a trunk of a tree. A plurality of arms is provided and each of the arms is coupled to and angles upwardly from the collar when the collar is positioned around the trunk of the tree. A screen is attached to the collar and each of the arms such that the screen forms a cone when the collar is positioned around the trunk of the tree. In this way the cone captures leaves falling from the tree. A pair of chutes is provided and each of the chutes is coupled to the collar. Each of the chutes is aligned with the cone to direct the leaves outwardly from the cone for bagging the leaves.

摘要： A debris-collecting apparatus includes a draft inducer operable to draw air and debris, an input portion for receiving incoming air and debris caused by operation of the draft inducer, and a bagging portion. The bagging portion includes a hood having an arcuate portion, a bag removably positioned below the hood and having an inner face, and a bagging passage for directing the air and debris from the input portion to the hood. The arcuate portion extends from the bagging passage to the bag such that the air and debris from the bagging passage travels along the arcuate portion and thereafter apply a dislodging force to dislodge debris collected at the inner face of the bag.

摘要： Debris-collecting systems and bagging apparatus for debris-collecting systems are provided. One bagging apparatus includes a primary bag and a dust skirt configured to wrap around the primary bag. At least an inner face of the dust skirt has an electrical charge. One debris-collecting apparatus includes an input portion, a bagging portion, and a draft inducer for drawing the air and debris through the input portion and to the bagging portion. The bagging portion has a hood, a primary bag removably positioned lowerly adjacent the hood, a dust skirt configured to wrap around the primary bag, and a bagging passage for directing air and debris to the hood from the input portion. The hood has a helical configuration extending from the bagging passage toward the primary bag. At least an inner face of the dust skirt is electrically charged. A frame having at least one wheel facilitates transportation.

摘要： A blower includes a first fan stage with a first housing that has a first plurality of stationary vanes and a first fan that has a first plurality of blades extending radially outwardly from a first hub. The first housing includes a first axial end and a second axial end opposite the first axial end. The blower also includes a second fan stage coupled to the first fan stage. The second fan stage includes a second housing with a second plurality of stationary vanes and a second fan that has a second plurality of blades extending radially outwardly from a second hub. The second fan stage includes a third axial end and a fourth axial end opposite the third axial end. The first hub and/or the second hub has a frustoconical shape that converges from the first axial end toward the fourth axial end.
