T955III Surface Miner Features & Benefits

Elevated operator visibility and comfort

The elevating rollover protective module cab features LEXAN glass, filtered and pressurized air, heating and air-conditioning. The cab’s vantage point allows an optimal view of the boom, trench and conveyor.


Superior ground penetration and low chain wear

A rotary power trencher drive motor and splined headshaft produce a low speed and high torque which provide maximum ground penetration and low chain wear for optimal production results.

Advanced technology for improved machine efficiency

SmartTEC performance monitoring assists operators with adjustments to machine controls to help improve efficiency and tracks the operational performance of the machine on a consistent platform across all machine models.
