Hitachi created its new ZX60USB-3 crawler excavator to bridge the gap between the ZX50U-2 mini excavator and the mid-sized ZX75US-3. With operating weights from 13,700 pounds the new ultra-short excavator with a swing boom would not be considered a mini excavator. Maximum dig depth is 12 feet 4 inches. The swing boom moves 80 degrees to the left and 60 degrees to the right. The 54-horsepower Yanmar 4TNV98 engine uses exhaust gas recirculation to satisfy EPA interim Tier-4 emission regulations. The ZX60USB-3 is available with either rubber or steel tracks.
