Tech-rich features need skilled use to shine.
Performance & Efficiency
HydrauMind and economy mode dial in fuel savings; KOMTRAX keeps tabs on uptime. Comfortable cab and auto-idle reduce operator fatigue.
In Comparison
Stronger and more capable than smaller mid-size excavators; easier on cost and mobility compared to full-size rigs.
Verdict
Smart, strong, and suited for high-output mid-size jobs. Not for ultra-tight access work or simplicity-only operations.
