This trencher is powered by a robust 420cc gasoline engine, delivering strong and consistent output to handle various complex ground conditions such as mud, compacted soil, and frozen layers. Even under high-load operations, it maintains stable performance. The durable chain system, composed of 27 tungsten carbide cutting teeth and 9 plow blades, combines high hardness with excellent impact resistance, improving trenching speed and precision while reducing the frequency of tool replacements.
