CAT 345 GC
Pros
- Designed as the GC (“General Construction”) variant with efficiency focus vs heavier models like 345C or 349.
- Good reach and depth for large trenching, earthmoving and general excavation work.
- 630 L/min flow supports heavy implement movement and attachments smoothly.
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.
