Evaluating the Hitachi EX60URG Mini Excavator from the 1990s
#1
Hitachi’s Compact Excavator Legacy
The Hitachi EX60URG is a compact excavator produced during the 1990s, part of Hitachi’s URG series designed for urban and restricted-access environments. Hitachi Construction Machinery, founded in 1970 as a division of Hitachi Ltd., quickly became a global leader in hydraulic excavator technology. By the mid-1990s, Hitachi had sold tens of thousands of compact units worldwide, with the EX60URG serving as a bridge between the ultra-compact EX30 and the mid-sized EX100.
The “URG” designation refers to “Urban Reduced Geometry,” a design philosophy that prioritizes minimal tail swing and compact dimensions without sacrificing digging depth or hydraulic performance. These machines were particularly popular in Japan, South Korea, and parts of Southeast Asia, and many were later exported as gray-market units to North America and Australia.
Core Specifications and Performance
  • Operating weight: ~6,000 kg
  • Engine: Isuzu 4-cylinder diesel, typically rated at 50–60 hp
  • Digging depth: ~4.2 meters
  • Bucket breakout force: ~4,000 kgf
  • Hydraulic system: Open center with gear-type pump
  • Swing radius: Reduced tail swing for confined spaces
The EX60URG was praised for its smooth hydraulic response, fuel efficiency, and mechanical simplicity. Unlike newer models with pilot controls and electronic diagnostics, the EX60URG relied on direct mechanical linkages and analog gauges—making it easier to repair in the field.
Terminology Explained
  • Gray-Market Machine: Equipment originally sold in one country and later imported unofficially into another, often lacking local support or documentation.
  • Open-Center Hydraulics: A system where fluid continuously flows through the control valves until a function is activated.
  • Breakout Force: The maximum force the bucket can exert when digging, critical for trenching and demolition.
Parts Compatibility and Filter Cross-Referencing
One of the challenges with the EX60URG is sourcing replacement filters and consumables. Many owners seek to cross-reference Hitachi part numbers with John Deere equivalents, as Deere and Hitachi shared manufacturing facilities and components during this era. For example:
  • Air filter: Often interchangeable with Deere 50-series compact excavators
  • Hydraulic filter: May match early Deere 490D or 690E models
  • Fuel filter: Compatible with Isuzu industrial engines used in both brands
However, part numbers are not always “universal.” Dealers may require the full serial number and machine variant to confirm compatibility. Some owners report success using aftermarket catalogs from Baldwin, Fleetguard, or Wix, especially when OEM parts are unavailable.
Field Anecdote and Practical Insight
A contractor in British Columbia purchased an EX60URG for site prep and utility trenching. He noted that the machine ran well but lacked documentation. After trial and error, he discovered that the hydraulic filter matched a Deere 490D, and the air filter was identical to one used in a Kubota tractor. He built a cross-reference chart and shared it with local mechanics, saving time and reducing downtime.
Another operator in New York retrofitted his EX60URG with a thumb attachment for handling debris. He tapped into the auxiliary hydraulic circuit using a diverter valve and mounted a foot pedal in the cab. The modification cost under $500 and dramatically improved versatility.
Manuals and Technical Documentation
Finding service manuals for the EX60URG can be difficult. Some online vendors offer digital downloads or CD-ROMs, but quality varies. Operators should seek:
  • Operation and Maintenance Manual (OMM)
  • Hydraulic System Schematic
  • Parts Catalog with exploded views
  • Engine Service Manual (Isuzu 4JB1 or 4JG1 variants)
While not always model-specific, manuals for the EX60-2 or EX60-3 can provide useful guidance. These models share many components with the URG variant, especially in the undercarriage and hydraulic layout.
Preventive Maintenance Recommendations
  • Change engine oil every 250 hours
  • Replace hydraulic filters every 500 hours
  • Inspect track tension monthly
  • Grease all pivot points weekly
  • Flush cooling system annually
Operators should also monitor swing bearing play and boom pin wear, especially on machines with over 5,000 hours. Replacing worn bushings and pins can restore precision and reduce stress on the frame.
Modern Comparisons and Lessons Learned
Compared to today’s compact excavators, the EX60URG lacks electronic diagnostics, auto-idle, and load-sensing hydraulics. However, its mechanical simplicity makes it ideal for remote work, rental fleets, and owner-operators who value reliability over refinement.
In 2022, a small contractor in Queensland restored an EX60URG for use in flood recovery. The machine performed flawlessly in muddy terrain, and its reduced tail swing allowed safe operation near structures. The contractor noted that while newer machines offer creature comforts, the EX60URG “just works.”
Conclusion
The Hitachi EX60URG remains a dependable and versatile compact excavator, especially for operators who appreciate mechanical transparency and field-serviceable systems. With proper maintenance, creative parts sourcing, and occasional retrofits, this 1990s workhorse continues to earn its place on modern job sites. Whether trenching, grading, or lifting, the EX60URG proves that good engineering never goes out of style.
