    Rugged Design

    Integrated front cast weight reduces the need for extended weight racks, no matter which attachment is used.

    Part of a complete microtrenching system that includes a specially configured RT45 or RT55 and a specially designed saw blade.

    Heavy-duty frame, ground drive components and backfill blade assembly ensure maximum durability and reliability.

    Planetary axles provide greater torque at the wheel and higher ground clearance.
