T858 COMMANDER® 3

Offset Track Trencher with Optional Features

Trencher - Pipeline | Vermeer T858 COMMANDER® 3

Trench up against guardrails, buildings, walls and other obstacles with the T858 offset track trencher. Powered by a 350 hp/261 kW Caterpillar C9 Tier 3 engine, it’s loaded with features that help improve efficiency on most jobsites.


Features and Benefits

  • Remove spoils more efficiently using the well-designed conveyor.
  • Trench more efficiently with less chain wear due to its low-speed, high-torque, splined headshaft motor and variable chain speed.
  • Improve job monitoring between the Murphy PowerView system and the exclusive Vermeer TEC 2000® Electronic Control System.
  • Enhance visibility and productivity with an enclosed cab that elevates the operator 3’/.9 m.
  • Increase operator safety thanks to the industry’s first Rollover Protective Structure (ROPS).
  • Vermeer Vantage Track Extended Care Service Program offers an optional 3-year/3,000-hour or 5-year/5,000-hour warranty on the components of the closed loop hydrostatic systems.
  • See your Vermeer dealer for comprehensive service and genuine Vermeer replacement parts.
