Disclosed is an excavating machine, representatively a tracked excavator, having a boom stick portion on which both an excavating bucket and a hydraulic breaker are mounted for hydraulically driven pivotal movement between first and second limit positions. The bucket may be operated independently of the breaker for digging operations. Similarly, the breaker may be operated independently of the bucket for refusal material- breaking operations. The same excavating machine may now use the bucket and breaker in a rapid and continuous exchange to permit frequent removal of small quantities of broken refuse material with the bucket, exposing the bucket and breaker to fresh refuse material. The excavating machine disclosed incorporates an impact resistant deployment system with bifurcated and lubricated trunnion pivots and an in-line pivot restriction, or stop. The system provides a breaker assembly connection that permits quick installation and removal of the breaker, and significantly greater durability.
