KobelcoEach of the Kobelco 27SR-3, 30SR-3, 35SR-3 and 50SR-3 compact excavators features an independent boom swing mechanism. One pump is dedicated to the swing circuit, which enables simultaneous operation of the boom, arm or bucket without any affect on swing operation. Ranging from 21.3 to 40.8 net horsepower, the zero-tail-swing SR-3 Series excavators weigh from 5,490 to 10,384 pounds and provide maximum dig depths from 8 feet 4 inches to 11 feet 9 inches.
