The CME-750X gives you the versatility to tackle almost any job

CME-750X Rubber Tire ATV Mounted Drill The CME-750X is a veteran of the drilling industry. In its first year of production in 1972, ten CME-750X drills were sold. And it remains in demand today due to its unique combination of versatile rubber tire all-terrain carrier and powerful mechanical drill. Since it’s not oversize, it is easily transported on a trailer. Any time of the day, any day of the week, without special permits. The rubber tires will not damage most paved surfaces. And the air-shift transfer case allows you to shift from 2-wheel drive to 4x4 when the work moves off road.



When the going gets rough, the CME-750X really proves its value

This all terrain drill lets you bid confidently on jobs that are hard to get to. It can eliminate the need for expensive access roads. You won’t find yourself wasting valuable time waiting for a bulldozer to pull your truck-mounted rig out of the mud. No more rescheduling jobs until weather improves, the ground dries up, or the snow melts. No more turning down jobs because you can’t get to the location.



Low ground bearing pressure also means less impact on the environment

CME-750X Rubber Tire ATV Mounted Drill 4WD ControlsGround bearing pressure is only 10.0 psi (0.70 kgf/cm²) to 12 psi (0.84 kgf/cm²), depending on tools on board. Compare that to the 35 psi (2.46 kgf/cm²) to 50 psi (3.52 kgf/cm²) ground bearing pressure of a truck-mounted drill. This high flotation lets you negotiate mud, snow, sand, and rocks…all with less damage to the terrain. That can be extremely important in environmentally sensitive areas such as parks, farms or golf courses.



Planetary front and rear axles with no-spin differentials and aggressive all-terrain tires… the ultimate combination for off road traction

Planetary axles put the gear reduction at the wheels. That means less stress on other drive train components. And no-spin differentials give you true 4-wheel pulling power. The 48 inch (122 cm) diameter tires are flexible and tend to flatten out on the bottom. This provides more ground contact and lower ground bearing pressure per square inch. They also tend to flex and envelope obstacles, rolling over objects that could cut into firmer tires. For optimum drilling performance, we designed the CME-750X to be heavier in the rear. So, to keep the ground bearing pressure equal on all four wheels, we put wider, 31 inch (78.7 cm) tires on the rear, compared to 25 inch (63.5 cm) wide tires up front. The front axle oscillates when traveling on uneven terrain, allowing all four tires to remain on the ground for better traction and load distribution. Hydraulic, wet disc type service brakes are located at each wheel for maximum stopping power. And since they are enclosed in the planetaries, they are not adversely affected by mud and water.



High ground clearance

CME-750X Rubber Tire ATV Mounted DrillThe underside of the CME-750X is protected by a steel belly pan with 22 inches (55.9 cm) of ground clearance. In order to keep the center of gravity as low as possible, we mounted the drill to the carrier frame, in between the tires. We also mounted the two water tanks underneath the deck. Their combined capacity is 220 gallons (833 L).



Single engine provides big savings

Power for both driving and drilling is provided by a 275 cubic in. (4.5 L) turbocharged and charge air cooled Cummins diesel engine. This single engine means bigger savings in your initial investment, as well as overall weight, space and maintenance. The engine power is distributed through a heavy-duty air-shift transfer case.



ROPS protection is standard

A roll-over protective structure meeting SAE specification J1040C is standard equipment on the CME-750X.



Integral design gives you a completely self-contained drilling unit with no compromises

Since we designed the carrier ourselves as an integral part of the overall drill, we were able to utilize all the space to the best advantage. The deck layout provides plenty of easily accessible storage area for augers, rods, and other drilling tools. The 126-1/2inch (321.3 cm) wheelbase accommodates 5 foot (1.5 m) augers in a rack below deck, between the front and rear tires. Lockable tool boxes are provided on both sides of the drill. The CME-750X can carry everything you need to get the job done.



Hydraulic feed and retract system provides 30,000 pounds (13,608 kg) of retract force and 20,000 pounds (9,072 kg) of down pressure

The vertical drive system uses twin hydraulic cylinders mounted in line with the drill spindle for precise control of force on the drilling tools. For exceptional drilling efficiency, the feed system has two separate control levers. One lever gives you manual control of feed and normal retract. The other lever is used for fast retract and detent feed. Retract rates of up to 84 feet (25.6 m) per minute let you add or remove drilling tools quickly. Pressure controls let you dial in specific feed rate and feed pressure. This system is extremely advantageous in core drilling and other operations that require precise control of feed. And since the two control levers are isolated, you can use the manual control for rapid retract without changing pressure settings for the detent feed control.



Standard 26 foot (7.9 m) mast

The distance from the sheaves to the ground is 26 feet (7.9 m). That means you can hoist 20 feet (6 m) of rods with clearance to spare. When the CME-750X is equipped with three hoists, you can pull 60 feet (18 m) of rods without having to lay any down on the ground or on the deck.



Control logic ― the key to operator productivity

Drilling and set-up controls are logically arranged on a control panel. For added convenience, we’ve staggered the more frequently used controls, such as the hydraulic hoists and sliding base levers. Dependable mechanical rotary drive provides 10,445 foot pounds (14,160 Nm) of rotary torque, plus high rotation speed when you need it. You get the torque you need for auger drilling, as well as rotation speeds over 745 rpm for rotary or core drilling applications. Other optional rotation speed and torque combinations are also available, including a high-torque rotary drive that gives you over 13,225 foot pounds (17,930 Nm) of torque at the drill spindle. With five forward gears and one in reverse, there’s a rotation speed and torque combination available for just about any situation. And since the transmission does not travel vertically with the spindle, you won’t find yourself unable to change gears at the top of the feed stroke.



Patented spindle brake stops rotation in an instant

An emergency spindle brake stops rotation in less than one revolution. This system is activated by two conveniently located push button switches as well as by strategically located wobble switches.



Slide base makes the job easier and quicker

The drill is mounted to the carrier on a hydraulically actuated sliding base. A 15 inch (38.1 cm) in-out movement allows you to quickly move the drill off the bore hole and align the sheaves for lifting tools with the cathead or any of the hoists. A 6.0 inch (15.2 cm) sideways movement gives you even more versatility. Aligning augers or rods when making connections is easy. Or if the bit drifts off at an angle when you start a hole, you can quickly straighten it to a vertical position. The slide bases can also save considerable time when setting up over an existing bore hole.
