Abstract
A quick attach accessory tool mounting frame is adapted to be mounted onto a quick attachment bracket and held in place. The adapter frame has plates mounting a hub to pivotally mount a powered auxiliary tool. The hanger is formed with spaced plates having upper edges that will abut against portions of the adapter frame to permit only limited pivotal movement of a tool supported by the hanger about a horizontal axis such that the operator can control the position of the auger after the hanger has pivoted against provided stops that limit the pivotal movement of the tool about one axis.
Claims13
A mounting device for mounting a powered attachment tool which is elongated along a working axis to a quick attachment bracket that is pivotally mounted on a prime mover, the quick attachment bracket comprising a saddle receptacle, and a mounting member spaced from the receptacle, the mounting device comprising an adapter frame, including a plate assembly having an edge portion for mating with the receptacle on the quick attachment bracket and a retainer spaced from the edge portion for retaining a mounting member of the quick attachment bracket, at least one support plate mounted on said adapter frame, a hub supported on the at least one support plate and having a hub axis parallel to a pivotal axis of the quick attachment bracket on which the adapter frame is placed, a hanger bracket for the powered attachment tool elongated along a working axis and pivotally mounted on said hub, said hanger bracket having end edges adjacent portions of said adapter frame formed to provide for a limited amount of pivoting of the hanger bracket relative to the adapter frame to permit the elongated tool to seek a vertical position under gravity when supported by the hanger bracket before an end edge engages the adapter frame.
A mounting device for mounting a powered tool that has an axis oriented vertically under gravity in a working position to a quick attachment bracket that is pivotally mounted on a prime mover, the quick attachment bracket comprising a saddle, and a mounting member spaced from the saddle receptacle, the mounting device comprising an adapter frame, including an assembly having a pair of side plates and a cross plate between the side plates, an edge of the cross plate mating with the saddle receptacle on the quick attachment bracket, and a receiver space between the side plates for receiving and retaining the mounting member of the quick attachment bracket, at a location spaced from the edge saddle receptacle when the adapter frame is positioned on the quick attachment bracket, a hub supported on the adapter frame and extending in a direction between the side plates at a position spaced from the cross plate and from the edge of the cross plate, the hub having an axis substantially parallel to the cross plate, a hanger bracket for a powered tool pivotally mounted on said hub between planes of the side plates, said hanger bracket having hanger bracket plates with end edges adjacent portions of said cross plate, the end edges being formed to provide stops that stop against the cross plate to limit the pivoting of the hanger bracket relative to the adapter frame about the axis of the hub, the hanger bracket being free to pivot when the powered tool is supported thereby to permit the axis of the powered tool to seek a vertical position under gravity.
