The narrow overall shape lets the HH40 work in tight quarters, on crowded jobsites, and in places other breakers can't. With few seals and moving parts, and no special tools necessary for repair, Worksite Pro breakers provide unsurpassed durability and simplified maintenance.Like all Worksite Pro attachments, this breaker is optimized to work with John Deere skid steers, compact track loaders, and compact excavators, and is compatible with most competitive models. Plus, it's backed by a one-year warranty and one-of-a-kind parts and service.
