UNFORGIVING CONDITIONS - MEET THE IRRESISTIBLE FORCES.
The XRS 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 Blower, Plow, 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.
