Mr. Manhole claims it only takes five minutes for its 800-pound cutter head to dry-cut through asphalt or concrete using any auger drive mounted on a skid steer, then lock on to the manhole casting and lift it out of the street. The adjustable cutter head fits a range of casting sizes. The maker says its unit works best on a compact track loader with auxiliary hydraulic flow of 20 gallons per minute. The system uses a plastic liner placed on top of the cone and cut level with the road slope using the Mr. Manhole Ring Saw. Manhole repairs sealed by a certified Mr. Manhole installer are guaranteed not to leak for five years. Suggested retail price for the system with all the accessories is $16,500.
