The 18" Groundhog Trencher is easy to use and operator propelled to offer controlled digging straight to the exact depth with an absolute minimum of effort.

It is suitable for a wide variety of ground, including sand, lawn, clay, gravel and road base and comes complete with the heavy duty ‘Shark Tooth’ chain made from carbide tipped rock type bits and is fully replaceable.

The Groundhog Trenchers slim design fits through narrow gates and doorways, and allows trenching close to walls and fences. The side cleaning auger stops material falling back into the trench. This saves precious clean up time, important for contractors who want to move onto the next job as soon as possible.

The Groundhog uses Shark Tooth chain with replaceable carbide-tipped bits and will dig a 3" (75 mm) wide trench to depths of 8", 12" & 18" (203, 305 & 460 mm) easily and quickly.

The Groundhog trencher also comes equipped with rollers that will significantly increase the life of the trencher digging chain while decreasing the risk of chain breaks. The chain rollers ride on the centre wheel of the roller while the side plates of the chain are guided by the wheel shoulders. In testing, sprocket jamming situations that would normally cause chain breaks were eliminated when using the roller.
