An attachment for a prime mover or backhoe which may be used to cut or crush material. The attachment includes a first jaw (6), being a fixed jaw, and a second jaw (7) being a free jaw which is pivotably connected to the fixed ja w (6), and at least three connectors which allow the attachment to be connecte d to the actuator arm of a prime mover or backhoe. These connectors include a head connector (11) adapted to provide a connection to the head of the actuator arm, and a driven connector (12) adapted to provide a connection to the driving beam of the backhoes actuator arm, and a strut connector adapted to provide a connection to the strut of the backhoes actuator. The head and driven connectors are associated with the fixed jaw and the strut connector is associated with the free jaw, where the head and driven connectors are connected to the prime mover or backhoe with a quickhitch. The arrangement i s such that when in use the distance between the driven and head connectors remains constant and the distance between the driven and strut or head and strut connectors varies.
