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 33 U
Pros
- Zero‑tail swing design — ideal for tight/urban work spaces.
- Efficient small‑diesel engine with good torque for its class (~28–29 hp).
- Multiple boom/arm options for deeper reach or higher cutting height.
