The AT40 All Terrain horizontal directional drill from Ditch Witch has an inner-rod design that provides a flush system to improve tool-joint durability and steering in hard-rock conditions. It also features RockMaster housing, and the modular design makes it adaptable to two different drill bit sizes, allowing a 2.875 and 3.5 regular api connection. A 160 hp Tier 4 Cummins diesel engine offers 40,000 pounds of thrust and pullback. A two-speed, rotational drive system produces 5,000 ft-lb of torque, and the drill is equipped with a 70 gpm, 1,100 psi mud pump to increase fluid flow from the pump to the swivel. 800-654-6481;
