2025 Ditch Witch® All Terrain AT120
All Conquering. All-Powerful. All Terrain.Whether you’re facing the world’s tightest timeline or the world’s rockiest mountain, there’s a drill for that. The world’s largest All Terrain drill, the AT120 was built to dominate the toughest challenges on the planet.
Features may include:
POWER- Powered by a 280-HP Stage V Cummins® engine, the AT120 packs the punch needed to dominate long bores and large diameter installs. The AT120 is loaded with 120,000 lbs of thrust/pullback, 15,500 ft•lbs of rotational torque and an additional 3,000 ft•lbs of inner rotational torque.
- The AT120 features patent-pending Virtually Assisted Makeup and Breakout (VAM) technology that makes it easier for operators to make up and breakout tool joints without the need for floats and sensors. The machine is also compatible with 20-foot drill pipe and its dual rod box design allows up to 360 ft. of drill pipe on board while making it easy to add or remove pipe as necessary.
- Designed for maximum uptime, the AT120 features a range of innovative improvements including a new displacement fluid pump for added fluid flow, an integrated wireline platform that allows the working hand greater access when connecting wire, and open top, angeled front wrenches that bring geater visibility of machine functions during operation.
- Another entrant in our storied family of All Terrain machines, the AT120 is made with that same All Terrain Technology that enables rock drilling at a low fluid level, decreasing jobsite waste, minimizing cleanup, and reducing environment impact.
- Best-in-class, fully-enclosed Ditch Witch cab features premium climate-controlled heat and air, heated suspension seats, added legroom and two LED touch screen displays for greater operator comfort and productivity. The cab also offers the best view to all critical vision points and a real-time carriage-position indicator that provides you insight to the exact carriage position for increased productivity and intuitive operation.
