Caterpillar has added two new models to its lineup of mini hydraulic excavators: The 4-tonne Cat® 304 and 5-tonne Cat 305 CR Mini Hydraulic Excavators deliver more power and performance with lower operating costs. These new models are the final machines to be reengineered to the Cat next generation mini hydraulic excavator line concept. From the 1.5- to 10-tonne class models, all 17-20 Cat mini hydraulic excavators in the range (depending on region) offer common features and consistent controls layout to simplify training and operator adaptation. Designed to deliver an improved customer experience, the Cat 304 and Cat 305 CR deliver more power to the pumps, higher bucket breakout forces, and deeper standard digging depths to increase performance by up to 20% over their E2 series counterparts. Their industry-leading grease intervals and extended filter service life, combined with common components throughout the line and flat, easy-to-replace side panels, deliver up to 10% lower owner and operating costs.   Built with a new reduced radius design, the 304 features a narrow, 1700-mm (66.9 inch) track width, 254 mm (10 inches) slimmer than the 304 E2, for more versatility and access to confined spaces. While narrower, the new 304 design increases performance, balance and stability of the 4-tonne class model. Its reduced radius allows for greater stability, both 360-degree and when traveling with loads, while its extra counterweight option takes the model to an even higher level of stability. The new engine on the 5-tonne class Cat 305 CR Excavator delivers nearly ...
