Advanced Load‑Sensing Hydraulics
Pressure‑compensated, load‑sensing (PCLS) hydraulics deliver smooth control, excellent multifunctioning, and increased craning capacity—helping operators work efficiently at lower engine speeds with precise machine response.
High‑Performance 4.5L Engine
Powered by the John Deere PowerTech™ EWL 4.5L engine, the 320 P‑Tier delivers strong power and torque without the need for a diesel particulate filter, helping improve reliability, simplify maintenance, and reduce operating costs.
Heavy‑Lift Capability for Demanding Jobs
An available Heavy‑Lift option increases lifting and craning performance, making the 320 P‑Tier well‑suited for underground utility work, material handling, and applications that demand extra stability and strength.
