Efficiently Powerful

The Cat® C4.4 engine provides cleaner, quieter operation while delivering superior performance and durability through a high torque design. Caterpillar's exclusive Intelligent Power Management system monitors operator input and power availability to keep the machine working at peak efficiency and provide the operator with greater customization to suit their application.


  • Enabled at the push of a button (Eco), saves on up to 5% on fuel consumption
  • Intelligent Hystat maintains maximum ground speed capability


  • Boosts engine speed by over 20%
  • Increases hydraulic cycle times and productivity

Work Made Easy


The optimized Z-bar linkage combines the digging efficiency of a traditional Z-bar with integrated tool carrier capabilities for great performance and versatility. Visibility to bucket corners and fork tips at ground level remain excellent while sight lines at full lift are maximized. Lift higher and reach further with the optional High Lift linkage.


Performance Series Buckets deliver up to 10% higher fill factors compared to previous models, better material retention for significant productivity and fuel efficiency improvements. The buckets feature a longer floor to take a bigger bite of the pile, an open throat to heap higher and curved side bars to help with material retention.
