JCB JS81
Pros
- Capable of ~7.1 m digging height and ~6.4 m reach — good for site work, trenches, and moderate depth excavation.
- Powered by ~76 HP Kirloskar engine with robust bucket/dipper tear‑out forces, delivering decent performance vs competitors.
- JCB has extensive dealer/service coverage in India, making parts and support easier compared to some smaller brands.
JCB NXT 150
Pros
- Larger 0.75 m³ bucket gives good material movement per cycle.
- Deep digging (~5.2 m) and high reach (~8 m) handles typical construction tasks comfortably.
- 600 mm wide shoe tracks and reinforced links help stability, especially in sloppy/soft conditions.
