Features
Move More Material with High‑Production Power
With up to 463 horsepower and a nearly 70‑metric‑ton platform, the 670 P‑Tier is built for large‑scale excavation, mass earthmoving, and quarry work where maximum productivity is critical.
Dig Deeper and Reach Farther
Offering digging depths up to ~30 ft., this machine is designed to handle deep trenching, large cuts, and bulk material movement with confidence across demanding applications.
Improve Operator Confidence With Visibility & Comfort
Standard camera systems with LED surround lighting provide enhanced 270° visibility, while a spacious cab and intuitive controls help operators stay productive and comfortable through long shifts.
