<p>An excavating machine (10), representatively a tracked excavator (10) has a boom stick portion (22) on which both an excavating bucket (36) and a breaker assembly (201) are mounted for hydraulically driven pivotal movement between first and second limit positions. The bucket (36) may be operated independently of the breaker assembly (201) for digging operations. Similarly, the breaker assembly (201) may be operated independently of the bucket (36) for refusal material-breaking operations. The same excavating machine (10) may now use the bucket (36) and breaker assembly (201) in a rapid and continuous exchange, to frequently remove small quantities of broken refuse material with the bucket (36), exposing the breaker assembly (201) to fresh refuse material. A deployment system (200) is disclosed having a mounting bracket (202) for closely aligned pivotal support of both the breaker assembly (201) and a single hydraulic cylinder (204).</p> |
