"Diverse Specialties takes skid steers and tractor-loaders to a new level with their innovative Boom-Grapple. This attachment combines grapple truck capabilities with the versatility of a skid steer and for a fraction of the cost.
"During the 2004 Florida Hurricane season with its millions of yards of storm debris, the need was evident. Despite the number of skid steers out there collecting debris, many of the trailers and trucks were too tall for standard buckets and grapples to load. The Boom-Grapple now makes it possible to reach easily over the sides of any road legal vehicle."
