Tata Hitachi ZAXIS 650H
Pros
- Good mid‑to‑large class excavator – Around 395 HP with ~58 t operating weight offers strong performance in heavy construction and mining tasks.
- High hydraulic capacity – Total main pump output ~868 L/min supports powerful digging and attachment operation.
- Solid reach and working range – Nearly 11.3 m ground reach and ~7+ m dig depth suits trenching, excavation, and loading.
LiuGong 921 Di
Pros
- Offers respectable digging depth (~5.9 m) and horizontal reach (~9.2 m), making it suitable for medium‑sized construction and earthmoving tasks like trenching, foundation work, and site prep.
- The boom and reach balance enables both digging and loading without needing heavy long‑reach modifications.
- Compared with heavier or lighter models, the 921Di’s boom reach fits well in the 20‑22 t excavator segment
