Buy or hire the E10z if...
The Bobcat E10z is a zero tail swing micro excavator built for confined internal and garden work, competing directly with the JCB 8008 CTS for the same narrow-access hire jobs. Its zero tail swing design lets it rotate its upper structure without the counterweight overhanging obstacles, unlike some other micro excavators of this size. It is typically hired for basement, extension and small landscaping work rather than bought outright.
