Features
Powerful Vertical‑Lift Performance in a Compact Footprint

The 331 P‑Tier combines a vertical‑lift boom design with strong breakout force and a high rated operating capacity, enabling precise material placement and efficient truck loading. Its compact track platform delivers excellent traction and stability, helping operators work confidently on soft ground while maintaining the performance expected from a larger machine.
Premium Cab Designed for Long Workdays

A completely redesigned, sealed, and pressurized cab delivers a quieter, cleaner, and more comfortable work environment. Increased glass area improves visibility, while ergonomically positioned joysticks, a redesigned switch module, and available heated and ventilated seating help reduce fatigue and keep operators productive throughout long shifts.
Additional Attachment Offerings for Optimal Pairing

Availability of over 100 John Deere attachments allows the 331 P‑Tier to move seamlessly between tasks such as grading, material handling, and site preparation. Advanced electrohydraulic controls make attachment operation smooth and responsive, while optional technology features—including grade‑management readiness—help operators work more efficiently and precisely as jobsite demands change.
