20 21 22 extending respectively along the top both sides and bottom of the scoop frame and being releasably attached thereto by means of plural nut bolt combinations 23 extending therough opposed cooperating holes 24 bottom attachment strip 22 is appropriately sized to fit immediately rearwardly adjacent rearward downturned margin 18 of bottom scoop element 14 so that it and the attaching nut bolt combination 23 cause a minimum of interference in moving the tool over some underlying supporting surface not shown the scope frame structure described is preferably formed of some rigid durable lightweight material such as sheet metal and particularly aluminum the rectangular configuration illustrated is not essential the scoop frame may be formed in various cross sectional shapes so long as scooping edge 15 of bottom scoop element 14 is substantially conformable with the surface which it is to clean commonly however this will require substantially linear configuration the dimensioning of the tool again is variable within wide limits but for common operation under normal conditions a width of about 26 inches and a depth forward rearward dimension of about 7 inches is preferred bag 10 is an elongate tubular structure having a peripheral dimension substantially the same as scoop frame 12 and at least not any smaller.
