MOBILITY
Rig moves are up to 80% faster and easier with the four-wheel drive diesel-engine powered carrier that moves at speeds of up to 10 km/h (6 mph).
QUICK AND EASY SETUP
A time saver when moving from hole to hole with unique maneuvering features like three available steering modes: four- wheel, two-wheel, and crab-like movement. Positioning is quick and easy using a handheld remote controller.

OPERATOR SAFETY AND COMFORT
Extensive insulation in the engine and pump compartments makes the MDR700 a quieter rig – 88dB while drilling and 74 dB when equipment is idling.
EFFORTLESSLY BREAK ROD JOINTS
The breakout system on the drill head uses a high-pressure oil and gear rack assistance to effortlessly break rod joints.
