FEATURES & BENEFITS
Low-speed, high-torque motor
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-ft (2.4-m) or folding 13-ft (4-m) dirt conveyors.
Optional warranty
Vermeer Vantage Track Extended Care Service Program offers an optional 3-year/3000-hour or 5-year/5000-hour heavy equipment warranty on the components of the closed-loop hydrostatic system.
Rotary power trencher drive motor
A rotary power trencher drive motor and splined headshaft produce low speed and high torque which provide superior ground penetration and low chain wear for better production results.
