New TerraTrencher

By Total Equipment Sales   


November 24, 2015 - Is it a Powered Hand Held Trencher, MiniTrencher, Ground Saw, or Portable Trencher? Call it what you will, but it does exist.

It is specifically known as TerraTrencher. From some perspectives, it is just a chainsaw that
is used for trenching. If the concept was truly that simple, then why has it not been commercially

It is inevitable, that at every trade show where the TerraTrencher is displayed, there is
someone that says that they or someone they know has built a trencher using a chainsaw. The common
thread being that almost everyone that has used chainsaws as trenchers has not had experienced long
term success. Why? There are a multitude of reasons including; chains that are not designed for digging,
underpowered units, poor air filtration (we’re not talking about sawdust), clutch failure or even
something further …chain speed.

TerraTrencher has been used as a commercial trencher by professional contractors in New Zealand for
the past 15 years. It has just been made available in the United States and Canada in the past year.

What differentiates TerraTrencher from a chainsaw is not the engine, but the components that fasten to
the engine. A standard chain saw has a steel bar and wood cutting chain that is attached to the engine.
The TerraTrencher has a chain driven gear reduction system in a dust protected housing that is fastened
to the engine. The dust protected housing also shelters the clutch from dirt contamination. A heavy
duty steel bar with a self sharpening trenching chain is attached to the gear reduction system. The gear
reduction system slows down the speed of the self sharpening trenching chain, extending the chain life
and supplying appropriate torque for the trenching process. The self sharpening chain is designed to
sharpen against the abrasive soil that it trenches. In addition, after market oil/foam filters are available
to better protect the engine from dust contamination.


All combined the hand held, portable TerraTrencher is under 35 lbs. Units are offered in three sizes, 16″, 20″ and 27″ long bars that will dig a trench 1.5″ wide. Further innovation includes a wheel support assembly that is available with a remote throttle control for long trench runs.

The TerraTrencher is the first truly portable powered hand held trencher that will allow you to trench in
those hard to access areas with very minimal ground impact. The resultant trench is clean and easily
accessible. The uses include irrigation, low voltage lighting, fiber optics, sheet drain installation, root
barrier installation, root pruning, and other electrical/plumbing applications.
