T855 Trencher

The Vermeer T855 COMMANDER® 3 hydrostatic trencher is your rugged trench digging tool. Designed specifically for 6' to 12' (1.8 m to 3.7 m) rock trenching jobs, the T855 is a great choice for utility, water, and sewer installation.

Features and benefits

  • Operate the rock trencher with less wear due to its low-speed, high torque splined headshaft motor. Put the spoils where you want them with the optional non-folding 8’(2.4 m) or folding 13’ (4 m) dirt conveyors.
  • Vermeer Vantage Track Extended Care Service Program offers an optional 3-year/3,000-hour or 5-year/5,000-hour heavy equipment warranty on the components of the closed loop hydrostatic system.
  • Vermeer dealers offer comprehensive service and genuine Vermeer replacement parts.
