Every Carrier
Trencher Attachments NZ
One attachment turns a tractor, excavator or skid steer you already own into a dedicated trenching machine — no separate self-propelled machine to buy, finance or store, from TrenchWorks, New Zealand's trenching equipment specialist.
Why an Attachment
Attachment vs. Self-Propelled Trenchers
A trencher attachment runs off equipment already on site — a tractor's PTO, an excavator's hydraulics, or a skid steer's high-flow circuit — rather than carrying its own engine and undercarriage. That avoids the capital cost of a dedicated self-propelled machine sitting idle most of the year, and means the same carrier can go back to its other work once the trenching job is done.
The right attachment is matched to the carrier you already have: tractor horsepower, excavator tonnage, or skid steer hydraulic flow. Browse by carrier type on tractor trenchers and excavator trenchers, or see every attachment together below.

Complementary Attachment

Not a trencher, but built to finish the job a trencher starts — filling the trench behind it.

Common Questions
Trencher Attachments: FAQ
What's the difference between a trencher attachment and a self-propelled trencher?
A trencher attachment mounts to equipment you already own — a tractor, excavator or skid steer — using its existing power source. A self-propelled trencher is a standalone machine with its own engine and undercarriage. Most New Zealand trenching jobs are well served by an attachment matched to an existing carrier, which avoids the capital cost of a dedicated machine.
Will a trencher attachment fit my existing equipment?
In most cases, yes — attachment trenchers are built to a range of tractor horsepower, excavator tonnage or skid steer hydraulic flow specifications. TrenchWorks can confirm compatibility with your specific carrier before you buy.
Can one attachment handle both trenching and backfilling?
They're typically separate attachments — a trencher cuts the trench, and a dedicated backfilling attachment like the AFT Dual Use Hopper fills it with sand or gravel afterwards, often run off the same tractor.
