For Release in North America and Europe: April 2016 
Release Number: 173PR16

The Cat® 304.5E2 XTC mini hydraulic excavator is the first model in the Xtra Tool Carrier (XTC) lineup. Built on the reliable E2 platform, the 304.5E2 XTC offers the same level of quality, performance, and operator comfort expected from a Cat mini hydraulic excavator. In addition, the machine has an innovative skid steer coupler interface for added versatility and work tool integration. This manual coupler allows for use of compact loader tools including: general purpose bucket, multi-purpose bucket, forks, dozer blade, brooms, power box rakes and trenchers. Coupler operation is controlled through a flick of the XTC switch on the right hand console in the operator station, then the standard right hand joystick then becomes your loader.

The 304.5E2 XTC allows operators to achieve improved productivity in material carrying applications, and also allows for reduced backfilling times. Due to the addition of the compact loader coupler interface, multiple applications may be achieved at a single job site with a single machine. This offering also improves efficiency of machine transport.

The 304.5E2 XTC also includes the standard features and benefits of the E2 model lineup. For example, automatic two-speed, 100% pilot controls, superior bucket rotation, blade float and safety are built into every Cat mini excavator. All operator stations are ROPS certified, and the Cat interlock system which prevents hydraulic movement when the safety bar is raised, adds further to operational safety, as do the automatic swing brake, retractable seatbelt and travel alarm (optional in Europe). Also, the COMPASS monitor includes a passcode protected security system, adjustable auxiliary flow control, site reference system all as standard. There is also a rearview camera option.

Finally, to increase the machine versatility even further, a mechanical or hydraulic quick coupler for the excavator front linkage (differentiate between the excavator coupler and loader coupler) is available for accommodating work tools such as augers and hydraulic hammers, and a thumb-ready stick is standard. Caterpillar offers a wide portfolio of performance matched work tools designed specifically to get the best out of your machine and deliver excellent value through high productivity and long life.
