Backhoe loader breakers and post drivers. Breakers go by pin size: three side-mount hammers for 45 / 38, 50 / 45 and 55 / 50 mm pins (front / rear) and the 1,356-joule JMA307EBH for 50 mm pins. Post drivers, 350 to 1,000 joules, come with the head for your exact backhoe and a front grapple that holds the post.
