Five compact-radius mini excavators now have Tier 4-I engines. Models 303.5E CR, 304E CR, 305E CR, 305.5E CR and 308E CR SB also have a new COMPASS control panel.
Five compact-radius mini excavators now have Tier 4-I engines. Models 303.5E CR, 304E CR, 305E CR, 305.5E CR and 308E CR SB also have a new COMPASS control panel. The digital panel includes an anti-theft system and an economy mode feature on the 3.5- to 5.5-ton machines that Caterpillar says can lower fuel use by 20 percent. The panel also has a continuous-flow feature for auxiliary hydraulics that maintains flow without operator intervention. Other refinements include a standard high-ambient cooling package, ergonomic joysticks, and the relocation of several controls for operator convenience. An end-damping system in both the boom and stick cylinders reduces shock loads and reduces material spillage.
