Overview
The TMG-SDT36 is a skid steer chain trencher capable of cutting a 6-inch wide trench to a maximum 36-inch depth. Earth and tungsten teeth handle dry, rocky, and compacted ground conditions. A boom and crumber assembly pulls spoil out of the cut and a 19-inch auger discharge conveys the material to the side so it doesn't fall back in. The result is a clean, orderly trench suited to pipe laying, conduit installation, sprinkler systems, and power or telecom line burial. At 880 lbs, this unit is a mid-weight trencher appropriate for mid-frame skid steers. Also available with side-shift capability as the TMG-SDT36S. SSQA universal mount.

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
Compact size fits small-frame machines (S70–S185 class) as well as mid and large-frame loaders. Universal SSQA mount works with all major brands.

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.

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.
