CAT 320D
Pros
- Proven Cat C6.4 ACERT engine with solid torque and power for mid‑size excavator tasks (earthmoving, trenching, loading).
- 5.7 m boom and ~9+ m digging height help in both shallow and medium depth work.
- Caterpillar’s dealer network is extensive — spare parts availability is usually strong globally.
Tata Hitachi NX 50
Pros
- With ~5.8 m max digging/dump height, it competes well with similar 5 ton machines.
- 5.19 ton operating weight makes it maneuverable on tight sites yet substantial enough for utility, landscaping, and light construction.
- Dual axial piston pumps and decent implement flow (~84 L/min) provide smooth, predictable action — appropriate for breakers, augers, and common attachments.
