The 300-hp HT300 heavy-duty, steel-tracked rock trencher is capable of trenching up to 10 ft. deep and 36 in. wide in the extreme conditions. The cruise-control system automatically adjusts ground speed as soil conditions change. A flywheel gearbox delivers maximum power to the trenching attachment on demand, while minimizing shock to the hydraulic system. The patented bit block digging system allows the digging tooth pattern to be customized to best fit the application. A fully enclosed cab with climate control protects the operator from excessive noise and vibration.
