Oskosh XRS Extreme Runway System

The Oshkosh XRS Extreme Runway System is a faster, simpler way to handle the most severe winter climate conditions. The sheer size is awe-inspiring, but it’s the capability that is most impressive. By combining a Plow, Blower, Sweeper and Air Blower in one unit, the runway clearing process is simplified. There’s less equipment, fewer operators and one platform for maintenance and training.
