Abstract
The trencher includes a wheeled carriage which has a steering mechanism and a digging which operates along an upright path. The trencher includes an upright boom structure that is mounted to the carrage and a digging chain support frame that can be raised and lowered relative to the trencher carriage along an upright path. The digging chain is mounted to the digging chain support frame by a powered sprocket wheel and a freely turning pulley wheel. The sprocket wheel the pulley wheel are positioned so that the digging chain describes an upright path. The path described by the digging chain is sufficiently upright so that the trencher can excavate a curved trench without the digging chain interfering with the walls of the trench to a degree that is sufficient to impede the operation of the trencher.
