The five new compact-radius Cat E Series Mini Hydraulic Excavators—303.5E CR, 304E CR, 305E CR, 305.5E CR and 308E CR SB—all use new engines that meet Stage IIIA/Tier 4 Interim emissions regulations and incorporate new features such as the COMPASS control panel, standard high-ambient cooling package, more efficient auxiliary hydraulics and redesigned control layout. All the E Series models are equipped with a new digital control panel called COMPASS (Complete Operation, Maintenance, Performance And Security System). Built into the COMPASS monitor are an anti-theft system which requires a five-digit alphanumeric password to start the machine, and an Economy Mode feature (3.5- to 5.5-ton machines), which potentially can lower fuel use up to 20 percent by adjusting engine speed. An automatic engine-idle system drops engine rpm to idle after 4 seconds of inactivity. All new E Series machines use an end-damping system in both the boom and stick cylinders to reduce shock loads and to reduce material spillage. E Series sticks are thumb-ready, with brackets welded in place and relief valves already built into the main valve. catrequests.com

The newest compact excavator in Bobcat Company’s lineup, the E26 has an operating weight of 5,690 pounds and an overall width of 59 inches. The excavator is powered by a 27-hp diesel engine that is Interim Tier 4 compliant. The unit’s minimal 0.8 inches of tail overhang allows the machine to fit in tight surroundings, and it leaves a lighter footprint than the 325 and 425 models it replaces. Ideal for landscapers and municipal projects, this excavator is a complement to larger machines when space is constricted, as well as perfectly capable of completing entire jobs on its own. 866.823.7898, bobcatadvantage.com
