Hitachi Compact Excavator ZX75US-7
The Hitachi Compact Excavator ZX75US-7 delivers the performance, smooth operation, and durability of larger excavators in a compact, reduced tail swing design. Built for residential, urban, and congested job sites, the ZX75US-7 provides unmatched access to tight spaces without compromising digging power, stability, or operator comfort.
As part of the next-generation ZAXIS-7 lineup, the ZX75US-7 incorporates advanced technology, improved fuel efficiency, and enhanced safety features to help operators work more productively. A larger, more comfortable cab, simplified maintenance routines, and smart attachment management features allow crews to spend more time working and less time adjusting equipment.
With outsized capabilities in a compact footprint, the ZX75US-7 is engineered to meet the demands of fleet owners and operators who need versatility, reliability, and long-term value from their equipment. Built with the same attention to detail as Hitachi’s larger excavators, this machine is designed to work where others cannot.
Product Highlights
Full-Size Power in a Compact Design
The ZX75US-7 delivers the digging force, hydraulic smoothness, and stability typically found in larger excavators, packaged in an ultra-short tail swing machine built to work confidently in tight residential, urban, and congested job sites.
Ultra-Short Tail Swing Access
A reduced tail swing radius allows operators to work closer to structures, utilities, and traffic lanes without sacrificing cab space, performance, or stability, making this machine ideal for confined environments.
Next-Generation Hydraulic Performance
Improved hydraulic output and refined control provide smoother operation, faster cycle times, and increased digging force compared to previous models, helping operators move more material with greater precision.
Advanced Attachment Management
Operators can save and recall up to 16 attachment presets directly from the in-cab monitor, significantly reducing setup time when switching tools and improving efficiency across multiple applications.
First-Class Cab Comfort
A larger cab with increased legroom and headroom, an air-suspension seat, adjustable console positioning, and improved visibility creates a more comfortable and productive operating environment throughout long workdays.
Intelligent Machine Technology
An 8-inch anti-glare LCD monitor provides access to machine settings, work modes, attachment presets, and a 270-degree camera system, enhancing control, visibility, and job site awareness.
