Bypassing Lockout and Diagnosing Safety Interlocks
The New Holland LX885 skid steer, introduced in the mid-1990s, was part of the brand’s push into high-performance compact equipment. With a 60-horsepower diesel engine and a rated operating capacity of 1,850 lbs, the LX885 became popular among contractors and farmers for its durability and ease of service. However, like many machines of its era, it relies on a series of safety interlocks to control hydraulic function—particularly the lift arms and bucket.
In one case, an LX885 that had sat idle for eight years was revived by jumping the starter and injection pump. The engine ran smoothly, and the machine moved forward and backward, but the lift arms remained locked. This pointed to a failure in the Electronic Instrument Cluster (EIC) or one of the safety switches.
Terminology Clarification
The LX885 includes a white rocker switch located above the operator’s right shoulder, facing downward. Flipping this switch to “Service” mode bypasses the safety interlocks, allowing the arms and bucket to function regardless of seat or seatbelt status. This mode should be used with caution, as it disables all safety restraints—meaning the machine can move or lift unexpectedly.
If the service switch restores hydraulic function, the issue likely lies in one of the following:
Repair Strategy and Long-Term Recommendations
New Holland, originally part of Sperry Corporation and later acquired by Fiat, has produced skid steers since the 1970s. The LX series was a major step forward in operator comfort and hydraulic performance. Though the LX885 is no longer in production, parts and manuals remain available through CNH Industrial and aftermarket suppliers. Many units are still in service today, especially in rural and agricultural settings.
Conclusion
Unlocking the hydraulic controls on a New Holland LX885 often involves diagnosing the safety interlock system. The service mode switch provides a quick bypass, but long-term reliability depends on restoring proper seat and seatbelt sensor function. With careful inspection and wiring repair, even machines that have sat idle for years can return to full operation—proving the resilience of New Holland’s engineering.

Terminology Clarification
- EIC (Electronic Instrument Cluster): The dashboard module that monitors and controls safety interlocks, including seat and seatbelt sensors.
- Lockout System: A safety feature that disables hydraulic functions unless certain conditions are met, such as operator presence and seatbelt engagement.
- Service Mode Switch: A manual override that enables full hydraulic function for maintenance or emergency use.
- Toggle Switch Panel: A hidden control panel often located behind a sliding door in the cab, containing fuses and override switches.

If the service switch restores hydraulic function, the issue likely lies in one of the following:
- Faulty seat switch
- Disconnected or corroded seatbelt sensor
- Failed EIC module
- Blown fuse in the upper-right cab panel
Repair Strategy and Long-Term Recommendations
- Replace rusted seat components and test continuity across the seat switch terminals.
- Clean and reseat all connectors to the EIC and fuse panel.
- Use dielectric grease on electrical contacts to prevent corrosion.
- If the EIC is non-functional, consider installing a manual override system with labeled switches and relays.
- Document all wiring changes and label circuits clearly for future troubleshooting.
