The stand-up, handheld machine comprised of a small engine/motor, an extended tubing housing a rotating internal transmission shaft, mounted to a speed reduction box. The speed reduction gearbox transmits rotation and torque to cutting and excavating blades via output shafts. Cutting blades cut and excavate soil to desired depth and width. Operator cuts and excavates trench by linearly moving machine along cutting surface. Operator controls speed of blades through throttle/speed control of power unit.
