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.
SANY SY27U
Pros
- A max digging reach ~4.85 m and height ~4.41 m is competitive for ~2.7 t mini class.
- Yanmar 20.4 HP engine with load-sensing hydraulics balances power and economy.
- Zero-tail swing design lets you work in tight, constrained spaces without rear overhang.
