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
SANY SY35U
Pros
- At ~3.8 t operating weight, it strikes a balance between power and maneuverability for urban/medium jobs.
- Makes working in tight spaces easier — minimizes side‑overhang when swinging.
- Powered by a Yanmar 3TNV88F (~18.2 kW / ~24–28 hp) with efficient load‑sensing hydraulics.
