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.
Tata Hitachi NX 30
Pros
- Higher engine power (~27.4 HP) than many comparable mini excavators, giving decent digging grunt.
- 2.62 m digging depth and ~3.92 m cutting/dump height make it capable for utility and small construction tasks.
- 58% gradeability and strong swing torque (490 Nm) help on sloped or uneven ground.
