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.
Yanmar VIO20-6
Pros
- Compact maneuverability with minimal rear overhang — great for urban/landscaping work.
- Eco-smart engine provides adequate power and smooth operation in small-machine applications.
- Multi-pump hydraulic system supports small breakers, augers, and tilt couplers.
