J&M’s new Model 4036 Drill Mast is the newest, heavy duty, cousin to the popular Model 3030 Drill Mast. Capable of drilling 36 in. diameter and 40 ft. deep, this unit can handle auger drives to 50,000 ft. lbs. of torque. Owned by APAC Construction, the drill mast is shown installing miles of sound wall in Florida. Mounted on a Komatsu PC400-7, the 4036 derives all its power from the excavator hydraulic system, yet requires NO modifications to the excavator hydraulics or structure.
