Volvo EC650
Pros
- Large bucket capacity (~3.2–4.4 m³) suitable for heavy earthmoving and quarry work.
- Robust undercarriage and planetary final drives typical of large Volvo excavators of the era.
- Older EC650 machines often have durable components and parts that can be sourced in secondary markets.
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.
