TRENCHER INTENDED USE
This machine is designed for digging trenches in “normal” ground of reasonably soft dirt and stones up to 3” (7.62cm)
in diameter. Ground with larger stones, high clay content, very hard packed, very dry, or in a frozen condition may be
unsuitable for normal trenching. Consider using a backhoe or other heavier equipment for such conditions.
