Tata Hitachi NX 50
Pros
- With ~5.8 m max digging/dump height, it competes well with similar 5 ton machines.
- 5.19 ton operating weight makes it maneuverable on tight sites yet substantial enough for utility, landscaping, and light construction.
- Dual axial piston pumps and decent implement flow (~84 L/min) provide smooth, predictable action — appropriate for breakers, augers, and common attachments.
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
