A combination bulldozer blade and materials handling bucket is mounted on the front end of an earth working machine. The bulldozer blade portion of the combination device is generally constructed and arranged to function in a substantially conventional manner. Pivotally mounted about the bulldozer blade and suitably provided with powered actuation means is a scoop having a concave bottom and parallel sides. Powered actuation of the scoop to a retracted position between the blade and the machine sets up the machine in its bulldozing mode. Having used the machine to bulldoze a pile of material into contact with the blade, the scoop is then actuated to its extended position, through the pile of material, thereby depositing the material encompassed by the scoop into an upwardly open bucket formed between the blade and the bottom and sides of the scoop. The material in the bucket is then moved by the machine to a suitable site and deposited by powered retraction of the scoop, whereby the blade functions as an ejector plate. Also, optionally attached to the blade is at least one lug for attachment of a fork to provide forklift capability or attachment of a chain or the like, to provide general haulage capability.
