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.
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.
