Information

2025 Ditch Witch® All Terrain AT40

ROCK HAS MET ITS MATCH.

Optimized for industry-leading performance and productivity when drilling in hard rock conditions, the AT40 has next-generation features so you can get increased jobsite cycle times, improved durability, and greater control.

Features may include:

ALL TERRAIN
  • All Terrain technology enables enhanced rock drilling at a low fluid level, decreasing overall jobsite waste, minimizing cleanup and reducing environmental impact. The inner pipe works as a mechanical motor, driving the bit during the bore, and the outer pipe thrusts the bit forward while steering the drill shaft. During backreaming, the outer pipe transmits full machine torque downhole.
POWER
  • Equipped with a 160-gross-hp, Tier 4 Cummins® diesel engine. With 40,000 pounds of thrust and pullback, the AT40 All Terrain provides 30 percent more thrust in a more compact unit than competitive models. Hydraulic platform utilizes the Ditch Witch-proven technology to provide the most efficient power downhole.
PRODUCTIVITY
  • Equipped with a 70-gpm, 1,000-psi mud pump, the AT40 All Terrain has increased fluid course from the mud pump to the swivel, for more downhole flow capabilities. The machine also includes a reversible pipe box for added jobsite versatility.
OPERATOR'S STATION
  • The AT40 All Terrain is equipped with the choice of a fully enclosed cab, with all tinted, glass side paneling, or an open operator’s station. Industry-leading telescoping cab places the operator at a precise angle, providing an enhanced view of drilling operations, including ground entrance, wrenches, shuttle-retract location, and rear connection.
ENHANCED SERVICEABILITY
  • With no grease zerks and easy access to all service points in one spot, maintenance is simplified, and total cost of ownership reduced. The AT40 All Terrain minimizes pipe-entry distance for increased support for the drill pipe as it enters the ground—this reduces wear on guide blocks and decreases the overall footprint on a job.
ENHANCED CONTROL
  • The AT40 All Terrain is equipped with a standard or heavy-duty modular stake down system that can now be feathered for more precise control. An advanced remote control gives operators the ability to set up the rig outside of the cab allowing more precise positioning of the unit on the job. The controller includes multi-mode ground drive; dual, independent stabilizers, stake down, cab traverse, and dual pivot.
SUPERIOR CUSTOMER SUPPORT
  • As with all Ditch Witch equipment, the AT40 All Terrain is backed by a worldwide network of dealerships you can count on for unmatched commitment to your success. From genuine Ditch Witch parts to factory-trained service and expert advice, your Ditch Witch dealership is your trusted partner.
