  • Operating Weight: 16,686 kg (36,787 lb.)


Simplified routing of the electrical and hydraulic systems improves reliability and eases service. Wiring and hoses are placed for protection against wear and damaging bends.

The easy-to-use CVT transmission automatically senses the load and delivers more torque and tractive effort as needed to maintain the desired speed.

New steering sensors control articulation speed when nearing frame-to-frame contact, cushioning impact during full articulation and improving operator comfort.

Productive new two-speed 4000 Winch delivers internal gear-ratio changes and line speeds similar to the two-speed 6000 Winch.

Exceptionally low diesel exhaust fluid (DEF) consumption rate reduces the need for DEF compared to some other EPA Final Tier 4/EU Stage V systems.
