2025 Ditch Witch® Ride-On Trencher Attachments RT70

Information

2025 Ditch Witch® Ride-On RT70

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 may include:

POWER
  • The RT70 features a 72-hp (53.7-kW) Yanmar
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.
INNOVATIVE 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.
