The EDCO TR-18 18-Inch Trencher is a powerful, compact, and manually-operated chain trencher specifically engineered for contractors, landscapers, and property owners who need to create clean, precise trenches up to 18 inches deep—quickly, efficiently, and with minimal disruption to the worksite. Renowned for its portability, ease of use, and rugged construction, the TR-18 stands out as a go-to choice for projects ranging from landscaping and irrigation to cable installation and utility runs.

Product Overview

EDCO’s TR-18 is designed to fill the gap between labor-intensive hand trenching and bulky, ride-on machines that require trailers and heavy transport. Weighing just enough to provide stability but compact enough for a single user, it easily fits in the back of most work trucks or vans, eliminating the need for a separate trailer and enabling seamless deployment to any job.

The machine comes standard with a 3-inch wide digging chain, and there’s an available upgrade to a 4-inch chain for wider trenching requirements. The unique spindle lowering system offers precise depth controls from 2 to 18 inches—perfect for projects that demand reliable utility depth but don’t want to over-excavate.

Key Features

• 18-Inch Depth Capability: Enables trenching from shallow 2-inch cable runs all the way to 18-inch deep utility trenches, all with a single tool.

• 3-Inch Standard Trenching Width: Suits most irrigation, power, or conduit projects; optional 4-inch wide digging chain available as needed.

• Spindle Lowering System: Crank-operated system lets operators dial in precise trench depths on-the-fly, ensuring consistent flow line for pipes or cable pulls.

• Ultra-Portable: Lightweight and sized for easy loading—no trailer required. The TR-18 fits through small gates, tight landscape access points, or narrow doorways, making it ideal for residential, commercial, and retrofit work.

• Obstruction-Friendly: Narrow design and forward reach let you trench close to walls, fences, or other immobile obstructions that would defeat wider or ride-on trenchers.

• Durable, Low-Maintenance Build: Built with EDCO’s longevity-focused engineering, including hardened digging chains and a frame designed to withstand years of field use.

Technical Specifications

Performance Benefits

• Time Efficiency: The TR-18 allows crews to trench in minutes what would otherwise take hours by hand, increasing profitability per job and reducing workforce fatigue.

• Clean, Consistent Trenches: Produces straight, uniform trenches—critical for laying pipe or conduit that must maintain a particular slope or separation.

• Reduced Disruption: Compact footprint and targeted digging create less landscape disruption, require less backfilling, and ease cleanup.

• No-Trailer Convenience: One person can transport and operate the TR-18, streamlining logistics on jobs where space and time are at a premium.

Applications

• Landscaping/Irrigation: Lay sprinkler lines, French drains, or garden lighting with minimal turf impact.

• Cable & Fiber: Utility companies and contractors can run phone, fiber optic, coax, or low-voltage lines efficiently.

• Utilities/Plumbing: Perfect for shallow gas or water lines in both new and established landscapes.

• Electrical: Residential or light commercial power lines, conduit routing, or EV charging prep.

User Reviews & Feedback

Contractors appreciate the TR-18 for its:

• Easy Operation – One user can operate and transport the machine, making solo jobs viable.

• Versatility – Ability to trench at variable widths and depths provides flexibility across a wide range of projects.

• Durability – Users note years of continuous operation with basic maintenance, thanks to hardened components and simple design.

• Profitability – Many report substantial labor savings and increased job throughput, ultimately cutting costs and increasing profit margins over the course of a season.

Maintenance Tips

• Daily: Clean the digging chain, remove soil/debris buildup, and inspect the tension and sharpness of the cutting teeth for optimal performance.

• Weekly: Lubricate key moving points and apply anti-rust spray to exposed steel. Regularly check chain and sprockets for wear, replacing when needed.

• Storage: Store indoors and cover to prevent weather damage; drain fuel and clean thoroughly before long-term storage.

Frequently Asked Questions

Q: Can the TR-18 carve through rocky or heavily rooted soil?
A: It’s optimized for standard soils, sod, and light clay. Very rocky or root-bound ground may slow progress—sharper chains and steady, slow feed help in dense conditions.

Q: What engine powers the TR-18?
A: Most models use reliable commercial-grade gasoline engines, but specs can vary—contact EDCO for current engine brands and horsepower.

Q: Is there a learning curve for first-time users?
A: Minimal—operators can learn to use the spindle depth system and safe trenching technique quickly; review the manual and wear appropriate PPE.

Q: How close to a wall or fence can I trench?
A: The compact design lets you trench mere inches from obstacles, which is not possible with most ride-on trenchers.

Conclusion

The EDCO TR-18 18-Inch Trencher is the professional’s choice for rapid, precision trenching in landscaping, utility, and construction applications. Blending portability, power, and user-focused innovation, it replaces hours of grueling manual labor with efficient, clean, and reliable results—transforming the economics and workflow of small to medium trenching projects for contractors and property pros everywhere.
