Excavator Trenchers by TGEC

TGEC builds hydraulic chain trenchers that mount on excavator booms in place of buckets. Four models (TG-T600 to TG-T1500) fit 2.5 to 12 ton machines, with adjustable widths and preset depths. Designed for trenching in soil, clay, and other suitable ground conditions.

Application Scenarios

Utility and cable installation – electrical, fiber, gas, water lines
Irrigation and drainage – agricultural and landscape systems
Landscaping and residential – sprinkler, lighting, small utilities
Road and highway – edge drains, culverts, crossings
Farming – irrigation pipe, drainage tile, underground wiring
Site development – storm drainage, service lines, groundwork

OEM and Bulk Supply

TGEC supplies chain trenchers factory-direct to dealers, distributors, rental companies, and qualified OEM partners. Four standard models cover 2.5 to 12 ton excavators, with custom mounting brackets available for specific excavator brands and quick couplers. Private-label configurations can be reviewed for production orders. Replacement teeth, sprockets, and applicable wear components are available subject to model and stock status. Contact our team with your model, excavator specs, quantity, and target market for a direct quote.

Frequently Asked Questions

What is an excavator trencher?+

An excavator trencher is a hydraulic attachment that mounts to the excavator boom and uses a rotating chain with cutting teeth to dig narrow, consistent-depth trenches. Unlike a bucket, which excavates wide and irregular openings, a chain trencher produces narrow, more consistent-width trenches for laying pipe, cable and irrigation lines. It is driven by the excavator auxiliary hydraulic circuit and is available in sizes for mini excavators through mid-size machines.

What excavator sizes fit a trencher attachment?+

TGEC chain trenchers cover excavators from 2.5 to 12 tons across four models. The TG-T600 fits 2.5 to 5 ton mini excavators, the TG-T900 covers 3 to 7 ton machines, the TG-T1200 fits 5 to 10 ton excavators, and the TG-T1500 covers 8 to 12 ton carriers. The excavator must have an auxiliary hydraulic circuit with sufficient flow and pressure to drive the chain motor. Verify your machine auxiliary hydraulic specs against the model requirements before ordering.

What can an excavator trencher be used for?+

An excavator chain trencher is used for digging narrow trenches for utility installation including electrical cable, fiber optic lines, gas pipes, water mains and irrigation systems. It is also used for drainage tile installation, landscape drainage, road edge drains, agricultural irrigation and site utility work during construction. The depth-control foot helps maintain a more consistent trench depth during operation, and the narrow trench profile can reduce the amount of material excavated compared with wider bucket excavation.

How do I choose the right excavator trencher?+

Start by matching the trencher model to your excavator operating weight and auxiliary hydraulic flow and pressure. Next, determine the required trench depth and width for your typical applications. The TG-T600 digs up to 600 mm deep, the TG-T900 up to 900 mm, the TG-T1200 up to 1200 mm, and the TG-T1500 up to 1500 mm. Cutting widths range from 150 to 300 mm depending on the model. Soil conditions, trench depth, required width, and available hydraulic flow all affect model selection. For more guidance, see our excavator trencher selection guide.

What is the difference between an excavator trencher and other trenching equipment?+

A ride-on trencher is a self-propelled machine dedicated to trenching, offering high production rates on large open job sites but requiring space to maneuver and transport. An excavator chain trencher is an attachment that converts an existing excavator into a trenching machine, which can be useful in confined or access-limited sites, urban job sites and contractors who already own an excavator. The excavator trencher can also switch back to a bucket for other excavation work, providing equipment versatility. A standard excavator bucket digs wider, irregular trenches and is less efficient for long, narrow utility runs. For a detailed comparison, see our trencher vs excavator guide.

Can TGEC supply trenchers for dealers and OEM customers?+

Yes. TGEC supplies excavator chain trenchers factory-direct to dealers, distributors, rental companies, and qualified OEM partners. OEM and private-label production is available with custom branding, paint colors and packaging. Custom mounting brackets can be reviewed for specific excavator models and production orders. Contact the TGEC sales team with your company details, target market and estimated volume for a customized supply proposal.
