Tata Hitachi Zaxis 38 U
Pros
- Excellent for tight sites (small footprint) and urban construction.
- Reliable Yanmar engine with decent torque for its class.
- Dual variable pumps allow smooth implement control.
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
