As the heir to our popular SOIL-XLS drill rig, the Acker REBEL XL continues its legacy with added features and a new mid-sized track system. Like all Acker rigs, it shines with its low-end torque and high-end speed, excellent production, and low cost to own. And with features like the Mast Dump and Engine Tilt, contractors can drill efficiently on sloped terrain where other drills dare not.
