Overview

Features

Uptime

  • 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.

Continuously Variable Transmission

  • 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

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

Productivity

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

Fuel Consumption

  • 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.
