The present invention includes a trencher assembly with a motor that directly drives a sprocket through the rotation of a shaft of the motor. The rotation of the sprocket drives both a digging chain and an auger assembly simultaneously. The ability to use a motor to directly drive the sprocket decreases the components necessary for a drive train of the trencher assembly to promote a compact design. This occurs because the sprocket is able to drive both the digging chain and auger assembly through the transfer of driving forces from the motor without any intermediate gearing, belts, rotating support structure, and the like.
