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.
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.
