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 320D3
Pros
- Strong engine performance for a 20-ton class excavator: 134 HP gross (100 kW), ~114 HP net. Great for heavy digging and lifting tasks.
- Typically well-insulated, ergonomically arranged operator cab with adjustable suspension seat, good visibility, and modern controls.
- Selectable power modes (Power, Smart, Eco) improve fuel efficiency depending on task.
