Excavator breakers and a post driver, on one page. The hydraulic breakers go from the 1,356-joule JMASB43EBH up to the 19,800-joule JMASB200EBH for 85–130-ton machines, and break rock, concrete and asphalt. The 1,000-joule post driver, for 7 to 10-ton excavators, drives fence and sign posts while a front grapple holds the post. Pick a type, then filter by machine weight.

A hydraulic breaker breaks rock, concrete and asphalt with a moil or wedge chisel. A post driver drives fence and sign posts into the ground. They are separate attachments, so a crew that does both needs both.
