Yanmar VIO50-6B
Pros
- Superior stability from robust X-frame undercarriage and increased weight, ideal for side lifts.
- Full cylinder protection and strengthened components lower total cost of ownership.
- Precise proportional controls, auto-deceleration, and low noise cabin boost operator comfort.
LiuGong 921 Di
Pros
- Offers respectable digging depth (~5.9 m) and horizontal reach (~9.2 m), making it suitable for medium‑sized construction and earthmoving tasks like trenching, foundation work, and site prep.
- The boom and reach balance enables both digging and loading without needing heavy long‑reach modifications.
- Compared with heavier or lighter models, the 921Di’s boom reach fits well in the 20‑22 t excavator segment
