TRENCHER INTENDED USE
This machine is designed for digging trenches in “normal” ground of reasonably soft dirt and stones up to 6”
(15cm) 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.
