The patented Terrasaw cuts a neat smooth-sided trench approximately 40mm wide and up to 700mm deep, depending on the model/trenching bar used. The offset transfer case positions the digging bar centrally, providing excellent ergonomic weight balance and maneuverability. The Terrasaw features a heavy duty trenching chain equipped with toughened steel self sharpening blades, providing high reliability and exceptional performance.

The winner of multiple National Fieldays Invention Awards, this Kiwi invention has created a whole new category of trenching tool.  The Terrasaw is the world’s smallest portable, convenient and cost effective power trencher.


Wider trenches, for large diameter pipes, concrete foundations etc. can quickly be produced with two or more parallel cuts, allowing easy spade removal of remaining soil. It is a simple to dig curves, right angles or custom shapes as required.

Now you don’t have to use large, expensive and cumbersome tractor-mounted or self-driven chain digging machines to do all of your trenching work. In the time it takes to transport conventional trenching equipment, you can take a Terrasaw out of your car, do the job and go home! The impressive digging speed and sheer convenience of a totally portable mini trencher you can carry with one hand means huge time and cost savings.
