Ditch Witch RT70

Ride-On Trenchers


How can we help?

(301) 874-5500

DITCH WITCH RT70 - RIDE-ON TRENCHER PULLING OUT ALL THE STOPS. 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. FEATURES AND BENEFITS POWER The RT70 features a 72-hp (53.7-kW) 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. PRODUCTIVITY 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 advanced cruise-control system senses engine load and automatically adjusts the ground drive speed to changing soil conditions for superior traction and maneuverability. INNOVATTIVE DESIGN 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. OPERATOR'S STATION 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. SUPERIOR CUSTOMER SUPPORT Your Ditch Witch equipment is backed by a worldwide network of dealers you can count on for unmatched commitment to your success. Similar models may be shown in addition to the featured model. Equipment may be shown with options. Specifications are general and subject to change without notice. If exact measurements are required, equipment should be weighed and measured. Due to selected options, delivered equipment may not necessarily match that shown.
