Operator Station
Superior comfort to keep you productive throughout the work day
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.
•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.
Joystick Controls
The boom swing and auxiliary hydraulic functions are located at your fingertips providing smooth, easy operation. They also eliminate foot pedals and free up the floor for more room for the operator’s feet. 100% pilot controls provide consistent flow and pressure throughout the life of the machine. This also allows all controls to be locked out while starting the machine.

Performance
Powerful digging with precise control
Stability
All four E Series models feature excellent 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 low for smooth, powerful performance and increased fuel eficiency.
200 Degree Bucket Rotation
Industry leading bucket rotation of over 200 degrees provides greater material retention during truck loading.
It also allows for easier vertical wall digging without having to reposition the machine.
Engine
High performance power train provides optimized engine horsepower and strong performance
Automatic engine idle automatically lowers engine revolutions when not in use to conserve fuel and lower environmental noise and emissions.
Automatic Two Speed
With the standard automatic two speed feature, the machine will automatically balance high speed and torque travel requirements based on the conditions to give the operator the optimum speed and control. The machine can be put in low gear if slower travel is desired while in tight conditions.

Compact Radius, Zero Tail Swing
Work in the tightest areas
Compact Radius
The compact radius design gives greater machine versatility and the capability to work within conined areas. This allows the operator to concentrate on the work being done without having to worry about damaging the back of the machine or other job site obstacles. On the 305E CR and the 305.5E CR, the upper body stays within 140 mm (5.5 in) of the undercarriage.
Zero Tail Swing
New to the E Series, the 303.5E CR and the 304E CR models feature a zero tail swing design. On these models, the radius of the upper body stays entirely within the width of the undercarriage.
