Powered by a Cummins QSB 6.7 Tier III engine rated at 190 horsepower and 2,300 revolutions per minute, the rig matches percussion power and feed to the rock. The unit features a carousel with rocker switch rotation and single joystick control. The carousel can handle up to six, 12-foot rods plus a 14-foot starter rod.
