The Standard Tail Swing Design Incorporates A Counterweight That Extends Further Back On The Machine For Greater Stability. The Standard Tail Swing Paired With A Fixed Boom On The 307e2 Provides Superior Reach And Lift. The Operator Environment Includes A High Quality Suspension Seat, Easy To Adjust Armrests And 100% Pilot Controls Which Offer Consistent And Long-Lasting Controllability.

High Definition Hydraulic System Provides A Load Sensing And Flow Sharing Capability Leading To Operational Precision, Efficient Performance And Greater Controllability. Power On Demand Provides Optimal Efficiency And Performance The Moment You Need It. This Automatic System Ensures Fuel Efficiency Through Appropriate Engine Rating To Meet All Operational Needs As Required.

Broad Range Of Cat Work Tools Make The Cat Mini Excavator A Versatile Machine, Able To Meet The Requirements Of Any Job Site. 180 Degrees Of Bucket Rotation Provides Greater Material Retention During Truck Loading And Easier Flat Wall Digging Without Having To Reposition The Machine.

Front Shovel Bucket Orientation Provides The Operator With More Ways To Get The Job Done Faster. Compass Control Panel Is A Standard Feature That Allows The Operator To Easily Adjust Auxiliary Flows To Achieve The Optimal Work Tool Performance, Activate Auto Idle For Improved Fuel Efficiency And Utilize The Security System To Ensure Protection Of Valuable Assets With The Simple Touch Of A Button. The Site Reference System Included In The Compass Monitor Provides Output From Pitch And Roll Sensors To Aid In Grading And Level Trenching. This Impacts Accuracy And Productivity For Job Site Finishing. Rearview Camera Improves Operator Productivity And Efficiency Through Increased Visibility, Making Work Easier To Complete.

Convenient Service And Maintenance Requirements Include Ease Of Access To Daily Check Points, 500 Hour Engine Oil And Filter Change Period, 500 Hour Grease Interval On Front Implement, S·o·ssm Oil Sampling Valve And Overall Long Term Durability.

All Cat Mini Excavators From 3.5 Metric Tons To 8 Metric Tons Are Rops, Tops And Top Guard Level Ii Certified And Include The Cat Interlock (hydraulic Lockout) System, A Certified Accumulator Which Allows For Auxiliary Pressure To Be Released, Making Connecting And Disconnecting Work Tools Safer And Easier, And A Travel Alarm. All Of These Safety Features Are Standard On The E2 Model Lineup (travel Alarm Optional In Europe).
