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.
CAT 305. 5E2
Pros
- Strong hydraulic performance & digging forces: Excellent digging and stick forces for a 5‑ton mini.
- Load‑sensing hydraulics: Smooth, responsive controls and efficient power delivery
- Durable CAT design: Heavy‑duty components and proven undercarriage.
