Fitted with a 482-horsepower, Tier 3 Deutz V6 diesel engine, the Bomag MPH122-2 asphalt recycler/soil stabilizer uses Bomag's proven hydrostatic rotor-drive system, designed, says the company, to optimize fuel efficiency and minimize maintenance. The operator can vary rotor speed from 100 to 170 rpm while the machine is under load, allowing the MPH122-2 to adapt on the fly to specific job conditions.
