I am looking to upgrade my excavator. I currently have a ZX 330 Hitachi with 16000 hours on it. Has anyone compared a cat 330d or 325d FM with a 330 Hitachi? Will the cat d-series outperformed a Hitachi? I do mechanical site prep during the winter and I need a machine that can multifunction with good cycle times and stick power. And also stand up to harsh conditions. Any advice is much appreciated
