QUALITY
The durable hoods and frame and the compact radius design of the 304E2 let you work comfortably and confidently in confined areas. The operator environment includes a high quality suspension seat, easy to adjust armrests and 100% pilot controls which offer consistent and long-lasting controllability.EFFICIENCY
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.VERSATILITY
Broad range of Cat Work Tools make the Cat Mini Excavator a versatile machine able to meet the requirements of any job site. Over 200 degrees of bucket rotation provides greater material retention during truck loading and easier flat wall digging without having to reposition the machine.PERFORMANCE
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 or economy mode 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.SERVICEABILITY
