A bagger attachment for grass mowers provides a powered auger having an inlet adjacent to the mower deck discharge opening and an outlet adjacent to the upper ends of bags mounted on hoop-like supports. The auger is shaped to produce a dense column of clippings and the like which densely fill first the bag adjacent to the auger discharge and subsequently the bag remote from the auger discharge. Air entrained with the clippings is exhausted before the columns are discharged, the upper ends of the bags are open and accessible to the mower operator so that he can observe the filling thereof and also insert stones and the like. The mower deck is provided with a raised wall portion and a baffle arranged to create optimum flow of the clippings into the auger. The upper side of the auger tube is provided with a hinged cover permitting access to the auger. Such cover is shaped to resist rotation of the clippings and improve auger efficiency.
In a mower having a rotary cutter element within a mowing housing, said cutter being adapted to remove material from the ground and expel such material through a discharge opening in said housing, the improvement comprising an auger tube having an inlet opening communicating with said discharge opening and an outlet end, container means associated with said outlet end to receive material moving therefrom, and an elongated powered auger extending along said auger tube from said inlet opening towards said outlet end, said auger operating to compress and move said material from said inlet opening and to discharge it through said outlet end, said auger tube providing a lower semicylindrical wall closely fitting a lower side of said auger and an upper wall portion spaced from an upper side of said auger having a noncircular shape, said material moving along said auger tube engaging said upper wall portion resisting rotation of said material with said auger and promoting movement of said material by said auger along said housing, a space between said auger and said upper wall portion accommodating movement of objects along said housing.
A mower attachment for mowers having a rotary cutter element rotatable within a mower housing and adapted to expel material through a discharge opening in said housing comprising an auger tube having an inlet opening adjacent said discharge opening and an outlet spaced from said inlet opening, an auger in said auger tube having a helical flight with a substantially uniform helix angle along the majority of its length and a decreasing helix angle at a discharge end thereof near said outlet end.
A mower comprising a mower deck having a discharge opening, rotary cutters in said mower deck mounted for rotation about a vertical axis and operable to eject material through said discharge opening, container means on said mower, and a powered auger operating to receive material through said discharge opening and to pump said material into said container means as a dense column, said container means providing a hoop, a bag having a mouth removably mounted around said hoop, support means supporting a lower end of said bag, said auger means operating to pump said material through said hoop into said bag, said hoop being open along an upper side thereof to permit a mower operator to observe the filling of said bag and to insert objects thereinto.
A mower system comprising a mower deck, blades operable to eject material through a discharge opening, auger means having an inlet adjacent said discharge opening and an outlet, said auger means operating to pump said material from said inlet opening and to discharge said material from said outlet as a dense column, container means including a first container adjacent said outlet and a second container on the side of said first container remote from said outlet, said column filling said first container, and material said first container forming a floor directing said column to said second container whereby both of said containers are filled with dense material.
A mower system comprising a mower deck having a discharge opening, rotary cutter means operable to mow and discharge mowed material through said discharge opening, an elongated powered auger means having an inlet aligned with said discharge opening and being inclined upwardly therefrom to an outlet, said auger means operating to receive material carried by a flow of air from said cutter means and to pump said material from said outlet as a dense column after exhausting said air from said material, said mower deck providing an upper wall inclined up from the remaining upper wall thereof to increase the height of said discharge opening.
