OVERVIEW

BENEFITS

FEATURES AT A GLANCE

PROVEN RELIABILITY

Cat C27 engine is built and tested to meet your most demanding applications.
Longer engine life and improved fuel efficiency with reduced rated speed.
Designed for longer life, rebuildability, and higher resale value.
Maximum responsiveness with Steering and Integrated Control (STIC™).
Moves more material more efficiently with improved power and control.
Durable construction withstands the toughest loading conditions and multiple life cycles.

PERFORMANCE AND PRODUCTIVITY

Two engine emission options are available that meet U.S. EPA Tier 4 Final and EU Stage V emission standards or U.S. EPA Tier 2 and EU Stage II equivalent.
Up to 10% more payload per pass on truck-loading applications with Performance Series Buckets.
Payload increase to optimize pass on 775 trucks.
Positive Flow Control (PFC) hydraulic system increases efficiency, bucket feel, and responsiveness with consistent performance.
Excellent visibility to the bucket edges and work area through a Z-bar linkage.
Planetary power shift transmission for maximum uptime.
Convenient, responsive, electro-hydraulic controls increase operator productivity.
Superior digging, higher bucket fill factors, reduced dig times.
Integrated steering and transmission controls.
Operators can check tire pressure during operation with any change sending a fault code to VisionLink®, preventing premature tire failure.

POWERFUL EFFICIENCY

Up to 54% fuel efficiency material per gallon of fuel (27% less fuel consumption).
Economy mode for reduced rated engine speed and reduced fuel consumption.
Positive flow-control hydraulics for full flow on demand at lower engine speeds.
Engine Idle Shutdown for less fuel used while idling.
Fully integrated electronic engine controls make your fuel go farther.
