TT Technologies
Designed for residential service, small diameter main installations, last mile operations and gas pipeline applications, the compact Grundodrill 4X offers 9,800 pounds of thrust and pullback. The drill features a dual hydrostatic pump system and a four-auger stake down system that provides greater stability. The Grundodrill 4X also comes with the exclusive Smart Vice system that performs vice cycling operations automatically. 800.533.2078,

Ditch Witch
With 100,000 pounds of pullback and 12,000 foot-pounds of torque, the 268-hp JT100 All Terrain is built for extended-range bores and installations of large-diameter pipe. The exclusive, patented two-pipe drilling system of the JT100 All Terrain enables the machine to complete successful installations in most ground formations, including solid rock. Two other exclusive features distinguish the JT100 All Terrain. One is a dual-pivot drill frame that allows for steeper entry angles without raising the tracks off the ground. This improves machine stability and keeps the operator’s station level. The other is the machine’s assisted-makeup feature that automatically adjusts carriage thrust speed with rotation when making up and breaking out drill pipe, which minimizes wear on pipe threads and extends the life of the drill pipe. 800.654.6481,

Central Mine Equipment
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,


A 65 hp Kubota diesel engine powers the compact D16x20 Series II. It provides 2,000 foot-pounds of rotational torque and 1,600 pounds of thrust/pullback. The onboard pump provides high flow in large-diameter bores for more efficient backreaming. Extendable tracks that adjust outward increases stability on uneven terrain with. Other features include dual joysticks integrated with all drilling function controls, the AutoDrill system with patent-pending Auto Resume, and a comfortable operator’s station. And visibility is enhanced while loading/unloading with a tethered ground drive controller. 888.837.6337,
