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 Bobcat machines but mounts to any skid steer or CTL with a universal SSQA quick-attach plate.

About Bobcat in Canada

Bobcat is one of the most recognized skid steer brands in Canada, with a dealer presence in every province. Their OEM attachments are engineered specifically for Bobcat machines but use universal SSQA mounts for cross-brand compatibility.

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.
