T655III Pipeline Trencher Features & Benefits

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.

Elevated operator visibility and comfort

The sealed cab has self-contained heating and air conditioning with sound attenuating foam.

The elevating cab allows optimal visibility and added comfort with the air ride seat.

It is also a rollover protective module (ROPM) and provides falling object protection (FOPS).

Continued performance on hills and slopes

An oscillating track frame allows the track to follow the ground’s contour, providing a vertical trench on slopes up to 10.5°.
