500 SeriesBoasting a 40 percent increase in power, the 500 Series Tier-2 mainline pavers feature a 240-hp Cummins QSB5.9 diesel engine, which meets all Tier-2 regulations for EPA and CARB, and Stage-2 European standards. The rubber-tired model features a 40-percent boost in load-carrying capacity, giving it (as well as the steel- and rubber-tracked models) the ability to handle 25-ton loads. For the first time, a proportional steering system is available for Tier 2 rubber-tire pavers.
