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.
Sona RDT-17
Pros
- At ~1.7 t operating weight, easy to transport and use in tight areas.
- Reliable engine brand commonly used in mini excavators.
- 1.8 m digging depth and ~2.7 m height are reasonable for 1.7 t machines
