A small, maneuverable, self-propelled tracked machine with a bucket or a digging tool. The machine is small and light enough to enter and be used in places, such as residential yards, in which traditional machines with buckets and digging tools, because of their size and weight, cannot be used. A three-stage gear pump powers the tracks and the boom on the bucket or digger. The machine has four outriggers to stabilize the machine during use, the outxiggers arranged substantially perpendicular to each other and at angles of approximately forty-five degrees from the longitudinal axis of the machine.
