Features
Heavy‑Duty Power With Improved Durability
The 300 P‑Tier builds on proven G‑Series architecture with significant front‑joint durability upgrades, including hardened pins, serviceable bushings, and enhanced sealing. These improvements help extend component life in abrasive conditions, reduce maintenance requirements, and maximize uptime on demanding jobsites.
Faster Cycle Times and Confident Control
Advanced hydraulics deliver strong digging force, smooth multifunctioning, and fast cycle times to keep material moving efficiently. Operators can engage power boost at the push of a button when extra breakout force is needed, while predictable hydraulic response supports precise trenching, loading, and material placement.
Improved Fuel Efficiency and Jobsite Visibility
Design enhancements—including electric on‑demand cooling fans and optimized hydraulic routing—help improve fuel economy by up to 7%, lowering daily operating costs. Optional camera systems with LED surround lighting provide enhanced 270‑degree visibility, helping operators work confidently in tight quarters and low‑light conditions.
