The Ditch Witch JT3020 All Terrain features a patented dual-drive pipe system that enables the machine to simultaneously steer and penetrate the soil. The inner pipe of the JT3020 All Terrain’s two-pipe drill string continuously turns the drill bit at 150 to 400 RPM, depending on the soil, resulting in exceptionally efficient boring. The JT3020 All Terrain can steer, drill and backream up to 650 feet in all types of soils, including solid rock. 800.654.6481, www.ditchwitch.com

This unit offers 6,000 pounds of thrust/pullback force and is capable of up to 500 foot-pounds of rotary torque, with a maximum rotary speed of 180 rpm. It weighs 2,600 pounds for minimum impact on turf and existing landscape. The patented Es!Lok system is integrated into the drill controls. An emergency shut down switch is located at the driller’s console. Powered by a 26-hp Caterpillar C1.1 diesel engine, the DD-65 has an onboard duplex mud pump that can pump 5 gpm at 650 psi. This unit uses 5-foot drill stem with an O.D. of 1.75 inches and can carry up to 150 feet of pipe. 800.527.6020, www.astecunderground.com

The CME-50DD is a mid-size machine that provides more than 50,000 pounds of thrust and over 9,000 foot-pounds of rotary torque. Features include all hydraulic controls, dual range thrust and rotation, floating carriage, patent pending open top heavy-duty vise and radio control tramming system. Efficient for both large and small diameter pipe installations, there are no chains that can stretch or break. And since the drill rod is on the same centerline as the rack and pinions, there is less stress on drill rods, the carriage and other components. 800.325.8827, www.cmeco.com
