The Terex 860 and Its Place in Backhoe History
The Terex 860 is a mid-sized backhoe loader that emerged during a transitional period in the global construction equipment market. Originally developed under the Fermec brand in the UK, the 860 was later absorbed into the Terex product line following Terex’s acquisition of Fermec in 2000. This model was designed to compete with the likes of the JCB 3CX and Case 580 series, offering a blend of European compactness and American-style loader power.
The 860 featured a side-shift backhoe design, allowing the rear boom to slide laterally for trenching close to walls or in tight spaces. It was powered by Perkins or Deutz diesel engines depending on the production year and market, typically delivering between 80 and 95 horsepower. Its hydraulic system supported both loader and backhoe functions with responsive control, and its cab was praised for visibility and ergonomic layout.
Sales of the 860 peaked in the early 2000s, with strong demand in Europe, Australia, and parts of North America. However, after Terex sold its construction division to Mecalac in 2017, support for older models like the 860 became fragmented, making service manuals and parts catalogs harder to find.
Why Service Manuals Matter
A service manual is more than a technical reference—it’s the lifeline for maintaining and repairing complex machinery. For the Terex 860, the manual includes:
Challenges in Locating Documentation
Finding a manual for the Terex 860 is complicated by several factors:
Field Work Without a Manual
One operator in New Jersey purchased a used Terex 860 for site cleanup and trenching. Without a manual, he relied on intuition and visual inspection to service the machine. After replacing a leaking hydraulic hose, he noticed erratic boom movement. Suspecting air in the system, he bled the lines manually—but the issue persisted. Eventually, he discovered a worn spool valve that required precise shimming, a detail only found in the service manual.
Another contractor in Ontario used a similar machine for snow removal. When the transmission began slipping in third gear, he guessed at fluid type and quantity, inadvertently mixing incompatible oils. The result was clutch pack degradation and a $2,000 rebuild—avoidable with proper documentation.
Recommendations for Owners
To maintain a Terex 860 safely and efficiently, consider the following:
Terex’s Corporate Journey
Terex Corporation began in 1933 as a division of General Motors, later evolving through mergers and acquisitions. Its construction equipment portfolio expanded in the 1990s and early 2000s, including backhoes, loaders, and compact excavators. The acquisition of Fermec brought European design sensibilities into the fold, but Terex eventually divested its construction line to focus on cranes and aerial platforms.
The sale of its backhoe division to Mecalac marked the end of Terex-branded loader production. Mecalac now supports some legacy models, though parts availability varies by region.
Conclusion
Owning a Terex 860 without a service manual is like navigating a forest without a map. While the machine itself is robust and capable, its maintenance requires precision and technical insight. By understanding its history, configuration, and support challenges, operators can make informed decisions and avoid costly mistakes. Whether through digital archives, dealer networks, or community knowledge, the key is persistence—and respect for the complexity of the iron.

Why Service Manuals Matter
A service manual is more than a technical reference—it’s the lifeline for maintaining and repairing complex machinery. For the Terex 860, the manual includes:
- Hydraulic circuit diagrams
- Torque specifications for critical fasteners
- Electrical schematics
- Troubleshooting flowcharts
- Maintenance intervals and fluid types
Challenges in Locating Documentation
Finding a manual for the Terex 860 is complicated by several factors:
- Multiple engine options (Perkins, Deutz) require different manuals
- Serial number ranges affect component compatibility
- Terex’s restructuring led to fragmented support channels
- Online listings often bundle unrelated manuals or omit key sections

Recommendations for Owners
To maintain a Terex 860 safely and efficiently, consider the following:
- Identify the serial number and engine type before seeking documentation
- Search for manuals by OEM part number, not just model name
- Verify that the manual includes hydraulic and electrical sections
- Use manufacturer-approved fluids and filters
- Keep a log of service intervals and component replacements
