HT220

HT220 Heavy Duty Trencher
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 you and your trenching machine going strong all day long.
Key Features
  • Exclusive flywheel gearbox delivers maximum power to the trenching attachment on demand while minimizing shock to the hydraulic system.
