A frame has a crosspiece with a pair of longitudinal branches, and is used for installing an adapter on earth moving equipment. This equipment has an implement support structure with one or more bearing plates for accommodating azimuthal rotation of a working implement. This working implement is removed from the implement support structure before attaching a frame there. The frame's crosspiece has walls that engage the bearing plates on the implement support structure. An adapter is rotatably mounted on the frame. Any one of a plurality of working accessories can be selected and installed on the adapter. For equipment that originally lacked bearing plates, a cross member with bearing plates is provided in a kit. The frame will then attach to the kit's cross member and to the implement support structure.

An attachment for use with a bucket of a prime mover comprises a base member having fixed shape in a longitudinal direction of the base member between first and second ends with first and second pivoting members pivotally connected at the first and second ends of the base member, each actuated for pivotal movement about a respective transverse axis by a distinct actuator. The second pivoting member forms a base for releasably receiving different attachment ends such as a secondary arm member carrying a respective pivoting member independently actuated of the base member's pivoting members that is disposed on a secondary arm member end distal to a connection end thereof for connecting to the base member, an extension member without any actuators and pivoting members, and a tool section which is designed for carrying out a specific function.
