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
