Overview
Gehl's 72-inch deep chain trencher is built for demanding utility and sewer installation on full-size skid steers. At 72 inches deep, this is Gehl's deepest trencher model — reaching sewer and municipal utility installation depths required on many Canadian commercial projects. The hydraulic chain drive powers through clay, gravel, and mixed Canadian soil conditions consistently. Gehl (Manitou Group) maintains a broad national dealer network in Canada with local service support. SSQA compatible for use on other skid steer brands.

Is This Right For You?
✅ Buy if…
- You trench through soft to moderate soil for utilities, drainage, or irrigation lines at 36–60 inch depth
- Your soil is clay, loam, sandy loam, or river bottom — chain trenchers cut fast in these conditions
⛔ Skip if…
- Your soil is solid rock, dense caliche, or Shield granite — chain links and sprockets wear out fast in rock
- You trench in deeply frozen Prairie ground regularly — rock chain at 3–5× wear rate makes winter trenching expensive
🔍 Also consider…
- Rock wheel trencher if your ground is consistently rocky or hardpan
- Standard auger if you're drilling individual holes rather than continuous trench lines
🔧 Machine Compatibility
Designed for Gehl machines but mounts to any skid steer or CTL with a universal SSQA quick-attach plate.
About Gehl in Canada
Gehl is a US equipment and attachment manufacturer with Canadian dealer coverage. Gehl attachments are designed to pair with their skid steer line but are compatible with other machines. Gehl dealers are present in most Canadian provinces and can support both machine and attachment service.
Care & Maintenance
- Inspect chain teeth after every use — worn teeth slow penetration dramatically and increase drive motor load; a full day's work can dull a chain in abrasive soil
- Lubricate the drive chain and boom sprockets before each use and again after every 4 hours of continuous trenching
- Check the boom bar for cracking or deformation after work in rocky or abrasive conditions — boom cracks propagate quickly under the bending loads of trenching
- Clean soil from the drive motor cooling fins and chain case after summer use — compacted soil on the motor causes overheating on long cuts
- Store the chain with teeth protected from ground contact — resting a chain on carbide tips on concrete chips the teeth before you've even used it
How to Connect
- Attach trencher boom using Bob-Tach
- Connect high-flow hydraulic couplers
- Test chain tension and direction before cutting
- Call 811 and verify all utilities located before first cut
⚠ Safety NoteCanada-wide: call 811 before you dig. Hydraulic trenchers may need 20-35 GPM depending on rock hardness.
⛏️ Before You Buy a Trencher
Most chain trenchers require high-flow hydraulics — confirming your machine's output is the single most important step before purchase.

- Call 811 before any dig — utility locate is required by law in Canada

Confirm Machine Fit
Verify your machine's hydraulic flow meets this attachment's requirements before ordering. High-flow attachments need 25–45+ GPM — standard flow machines won't run them properly.
