Features
Built‑In Technology for Accuracy and Productivity
The 350 P‑Tier is available with SmartGrade™ technology, giving operators access to integrated grade guidance and control to reduce rework and minimize grade checks. By helping operators achieve target grade faster and more accurately, SmartGrade supports consistent results across operators of varying experience levels.
High‑Output Performance for Heavy Material Movement
Powered by a 271‑hp John Deere PowerTech™ engine, the 350 P‑Tier delivers the muscle needed for high‑production excavation, trenching, and mass material handling. Strong digging forces and fast cycle times help crews move more material efficiently while maintaining smooth, predictable machine response under heavy loads.
Operator Confidence Through Visibility and Attachment Flexibility
Standard right, rear, and left cameras with LED surround lighting provide enhanced 270‑degree visibility around the machine, improving awareness in busy or low‑light jobsites. A hydraulic coupler‑ready option allows operators to quickly switch attachments from the cab, boosting versatility and keeping production moving across changing jobsite demands.
