Best For

Suited to These Applications

Fibre optic installation
Water pipelines
Drainage and irrigation
Utilities

The MH45 fits 8+ tonne excavators, digging three to five times faster than a bucket while producing clean-cut, narrow trenches with finely cut spoil for efficient backfilling. It's the practical choice for fibre optic, water and drainage installation where a smaller carrier machine is already on site.

Why Consider It

3–5x faster than digging with a bucket
Clean-cut, narrow trenches with finely cut spoil
Standard or narrow chain options to suit the application
Fraction of the cost of a self-propelled trencher

Is This the Right Machine for Me?

The MH45 is built for 8+ tonnes, trenching to 0.8m / 1.0m / 1.2m at widths of 125–200mm (64–84mm narrow option). If your project sits within that range it's a strong candidate — but ground conditions, site access and the exact outcome you need all matter too. Use the Find My Trencherquiz (on the right on desktop, or in the menu on mobile) for a starting recommendation, then talk to TrenchWorks to confirm it's right for your site before you buy. See the Trenchers NZ buying guide for how this machine compares across the full range.
