TMG-SDT72 72-Inch Deep Trencher for Skid Steers

Overview

The 72-inch-inch chain trencher cuts utility, irrigation, and drainage trenches in Canadian soil. TMG Industrial is a Canadian company based in BC with a nationwide dealer network and direct online sales, making parts and support easy to access across Canada. Tungsten carbide teeth handle hard clay, gravel, and rocky sub-soil that disc trenchers struggle with. Trench width and depth capacity depend on the selected chain configuration. Available direct from TMG Industrial Canada (tmgindustrial.ca).

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.

About TMG Industrial in Canada

TMG Industrial imports and distributes a broad range of construction attachments from its Canadian warehouses, offering competitive pricing with delivery across Canada. A popular choice for contractors who want solid value without long lead times.

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

  1. Attach trencher boom using Bob-Tach
  2. Connect high-flow hydraulic couplers
  3. Test chain tension and direction before cutting
  4. 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.
