Excavators

Caterpillar 303.5ECR


Comfortable Working Environment

Spacious and comfortable operator station with excellent visibility and legroom keeps the operator comfortable and reduces fatigue. Standard features include:

  • Reclining suspension seat with adjustable wrist rests.
  • Pilot operated controls on all services including travel levers and dozer functions.
  • Two post canopy design for better visibility to the work area.
  • A pattern control changer (not available in all regions) is accessible from the cab to switch between excavator and backhoe style controls.
  • Ample storage space under the seat that can be locked for added security.

Stability

All four E-Series models feature increased stability, while maintaining the compact radius design. This increased stability leads to more productivity and versatility through the use of heavier work tools and the optional long stick.

Fast, Powerful Digging with Load Sensing Hydraulics

High digging forces and fast cycle times deliver the productivity that your job demands. Load sensing hydraulics optimize flow for smooth, powerful performance and increased fuel efficiency.

Engine

High performance power train provides optimized engine horsepower and strong performance. Engine meets U.S. EPA Tier 4 Interim and EU Stage IIIA emissions requirements. Automatic engine idle automatically lowers engine revolutions when not in use to conserve fuel and lower environmental noise and emissions. The E-Series models feature an engine kill switch conveniently located in the cab and accessible from ground level.

 

 

The Cat 303.5E CR delivers high performance in a compact radius design to help you work in the tightest applications.
