Features

Performance

The 785G 3512E HD engine gives you the choice of power ratings: 1,450 hp to match your current fleet performance or 1,600 hp for faster cycle times. Advanced Productivity Electronic Control Strategy for Transmission delivers a smoother ride, better acceleration and gear optimization.

Safety

Standard Cat® Detect system, LED lighting, 600 mm (24 in) wide walkways, guarding of rotating components and hydraulic brake system with enhanced traction control system. Optional Working at Heights and Powered Access stairway.

Serviceability

Modular HVAC system, modular radiator, improved ground level serviceability, oil sight glass, 1,000 hour hydraulic filter, and Tier 4 SCR system improves serviceability and reduces downtime.

Operator Environment

New, quieter and larger, ergonomic deluxe cab. Electronic transmission controls and Cat comfort seats provides a smoother ride. Full size trainer door and improved head clearance on platform.

Operating Cost

Improved 3512E HD engine meets U.S. EPA Tier 4 Final emission standards, and the features Cat Selective Catalytic Reduction (SCR) system that provides the least Total Fluid Consumption cost with greater reliability.

Tire Options

With 36R51 tire option, particularly flat long haul high speed applications can take advantage of higher payload and higher TKPH.
