Designed for durability, safety, and ease of operation, the Nitro surprised even the experts. The Nitro works by hydraulically compressing nitrogen gas, transferring this energy directly to the hammer head, a revolutionary technology in the fence industry. The safest driver on the market, all controls are handled from the cab of a skid steer. With only 2 inches of stroke, the unit drives posts rapidly with hydraulic down pressure and 500-800 beats per minute.
