RT70

RT70 Heavy Duty Trencher
Powered by a 72-hp Yanmar® Tier 4 Stage V-Compliant diesel engine, the RT70 is built for heavy-duty trenching, plowing and microtrenching jobs with tight fits and even tighter schedules.
Key Features
  • The RT70 features a 72-hp Yanmar® Tier 4 Stage V-Compliant diesel engine, delivering max power and productivity. Exclusive 3-speed shift-on-the-fly lets operators work seamlessly without stopping to shift – like on competitive units.
  • Crab and coordinated steering modes make working easier, letting operators turn with a steering wheel – versus two separate levers. A push-button return to center automatically returns the rear axle to center while an advance cruise-control system senses engine load and automatically adjusts the ground drive speed to changing soil conditions for superior traction and maneuverability.
  • A modular, heavy-duty track-frame design provides a low center of gravity for increased stability, production and drawbar. The design lets you easily interchange between tires and tracks, saving time and extra labor. Plus, a patented centrifugal cooling system pulls all exhaust away from the operator’s station, keeping you more comfortable during long work hours.
  • Featuring an open design, the operator’s station features a 120-degree swivel seat, more leg room and enhanced visibility. A 4.3-inch color LCD engine display provides all engine information and diagnostics, increasing ease-of-operation.
