INTENDED USE
The STK 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 frozen
may be unsuitable for normal trenching. Consider using a backhoe or other heavier equipment for such
conditions.
