Abstract
A trenching machine has an elongated chain type digging implement that is pivotally mounted for vertical adjustment and movably mounted to a main frame thereof for lateral adjustment. The pivot coincides with the power shaft, and the elongated chain type digging implement is supported so it can be moved laterally in order to position the digging implement adjacent either side of the digging machine main frame and anywhere therebetween to excavate closely adjacent to buildings and other structures. The mechanism for moving the digging implement can be manually actuated by a hand crank arrangement. The main frame of the machine can be tilted laterally to either side to align the digging implement to excavate a vertical ditch. The tilting of the machine also makes it easier to manually move the digging implement laterally.
