Track Trenchers & Rock Saws: Ditch Witch HT220
The 220-hp HT220 is the heavy-duty track trencher you need when tackling big underground utility installations on tough terrain, such as wind-farm construction and installation of pipelines and energy-distribution facilities in remote locations.
The HT220’s climate-controlled cab and 114-gallon fuel tank help keep the operator trenching all day long. A flywheel gearbox delivers maximum power to the trenching attachment on demand while minimizing shock to the hydraulic system. Forged, heat-treated, high-alloy steel headshaft is guaranteed for life. Reversible conveyor effectively deposits spoils on either side of the trench. Trencher stabilizers effectively isolate vibration in rock and other harsh conditions. Reliable cruise-control system automatically adjusts ground speed to changing soil conditions. Patented bit-block digging system lets you easily customize your digging tooth pattern to best fit your application. A sturdy undercarriage is designed to withstand the rigors of trenching on rock-laden jobsites. 800.654.6481, www.ditchwitch.com
