The Hitachi Compact Excavator ZX85USB-5H is built for operators who need serious performance in residential and congested job environments. Its reduced tail swing design allows confident operation in tight areas while maintaining the digging force, hydraulic smoothness, and stability expected from larger Hitachi excavators.
Designed for versatility and maneuverability, the ZX85USB-5H provides strong breakout force, responsive controls, and efficient operation in an easy-to-handle package. Whether working near structures, utilities, or restricted access areas, this machine delivers the power and reliability contractors depend on without sacrificing control or comfort.
Engineered with the same quality standards as larger models from Hitachi Construction Equipment, the ZX85USB-5H offers a balanced solution for crews who demand performance and practicality in one machine.
