Vermeer T858III Commander® Trencher

It’s a big machine with a bad attitude.
The Vermeer T858 Commander® track trencher is a rugged rock-trenching solution. The T858 offset capability gives utility, water, and sewer contractors the additional access to trench alongside job site obstacles such as guardrails, kerbsides, buildings and walls with greater ease and precision. Put the T858’s 350hp (261kW) CAT C9 TIER III engine to the test on even the toughest trenching jobs.


  • Boom top rollers provide less friction between the digging chain and the top of the boom. This helps to decrease chain wear and improves usable horsepower to the digging line.
  • A curved cross conveyor provides more spoil capacity with slower belt speeds, which helps increase belt life.
  • The elevating ROPM cab offers increased operator visibility of the trench and the machine. The cab folds for easier transportation. The pressurized/filtered air, heat/air conditioning, and optional radio can offer greater comfort for the operator in all types of conditions.
  • These cab features contribute to greater operator comfort.
  • A proven high torque, powerful, and efficient hydrostatic transmission.
