Less than 40,000 pounds with virtually no counter-swing, the standard MR 5050 is a legal load in all of the 50 United States and best of all, it is built in the United States. Powered by a John Deere diesel, the MR 5050 has numerous kelly and mast configurations to meet different demands. The MR 5050 comes standard with 50,000 ft/lbs of "useable" hydraulic torque and a standard depth capacity of 50 feet. The MR 5050 can do 95 percent of the jobsite drilling for a fraction of the cost of the competitions bigger, heavier, slower rigs.
