The Ammann ART 240 Pneumatic Tired Roller does more than lower emissions. The EU Stage V / U.S. EPA Tier 4f machine provides all the key benefits of other Ammann tired rollers, including consistent coverage and even weight distribution. The propulsion system and rear drive axle provide the necessary power, whether working with or without ballast. Four ballast options and the air-on run system ensure the machine is properly matched to the jobsite. The machines are easy to handle, helping operators of all experience levels succeed.
