CAT 321
Pros
- 136 HP Cat C3.6 engine delivers strong digging performance.
- An advanced electrohydraulic system improves cycle time.
- Eco Mode and Intelligent ECM help reduce fuel consumption
Volvo EC140DL
Pros
- Multiple boom+arm combinations allow tailoring reach and depth for varying job requirements — from general digging to loading trucks at height.
- With a ~112–114 hp engine and solid hydraulic flow (~246 L/min), the EC140DL handles typical excavator duties efficiently
- Volvo cab & hydraulics are known for comfort and smooth control, reducing operator fatigue on long shifts. (Industry standard for Volvo D‑series)
