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 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.
