Mini excavators can dig basements, bury downspout lines, install electrical services, trench service lines, auger holes for trees or grapple obscenely big, decorative rocks. Today’s mini or compact excavator has become one of the world’s most nimble and versatile diggers and attachment-takers. Defined as an excavator under 6 metric tons (although we cover a few bigger ones as well), these are small excavation machines engineered with an undercarriage and tracks, a long digging arm and a cab or ROPS enclosure. Typically, with a dig depth between 5 and 20 ft and an operating weight between 2,000 and 20,000 lbs, compact excavators can fit into cramped worksites and still give big dig power. These units have grown so popular that the number of manufacturers offering models is overwhelming. To help out, here’s a quick list of the latest mini ex products on the market right now.
Wacker Neuson EZ36 and EZ26
Wacker Neuson continues to optimize its excavator line with the addition of two models that are built for operator comfort, stability, power and serviceability. The 3.6-ton EZ36 and 2.6-ton EZ26 compact excavators with minimal tail swing designs are versatile machines for a variety of applications. With best-in-class dig depth (11 ft, 6 in.) and reach (18 ft, 6 in.), the EZ36 is highly productive and offers the performance of a conventional track loader with excellent maneuverability and stability on a minimal swing machine. The EZ26 is ideal for working in tight spaces and is a great choice for landscape and backyard projects. The EZ26 has a dig depth of 9 ft and a maximum reach of 15 ft, 5 in.
