New Holland and Its Telehandler Legacy
New Holland, originally founded in Pennsylvania in 1895, became a global agricultural and construction equipment powerhouse after merging with Fiat and later CNH Industrial. By the early 2000s, New Holland had expanded its product line to include telehandlers—versatile machines designed for lifting, loading, and material handling across farms, construction sites, and industrial yards.
Many of New Holland’s telehandlers were manufactured in collaboration with European OEMs, particularly Manitou and Fermec. These partnerships allowed New Holland to offer rebadged models with proprietary branding, but often retained the original manufacturer’s components. This hybrid sourcing strategy, while efficient during production, created long-term challenges for parts support—especially for machines built between 1995 and 2005.
The Challenge of Locating Obsolete Components
One common issue faced by owners of older New Holland telehandlers is the inability to source discontinued electronic or hydraulic components. A notable example is the boom sensor with part number 85816651—a proximity switch used to monitor boom position and ensure safe operation.
When New Holland ceased support for this part, technicians were left searching aftermarket vendors, vintage warehouses, and European suppliers. Some vendors claimed to have stock in legacy inventories, but access was restricted due to internal cataloging or regional distribution limits.
Understanding the Boom Sensor Function
The boom sensor in question is a proximity switch, typically operating on a 12-volt DC circuit. It plays a critical role in safety interlocks, preventing boom movement under unsafe conditions or during startup diagnostics. If bypassed, the machine may operate temporarily, but risks violating safety protocols and damaging hydraulic components.
Terminology clarification:
When OEM parts are unavailable, technicians may consider retrofitting a compatible proximity switch. Key parameters to match include:
Best Practices for Sourcing Legacy Parts
To improve success when sourcing obsolete New Holland components:
In one case, a farm equipment dealer in Ontario had a telehandler parked for months due to a failed boom sensor. After exhausting OEM channels, he discovered a compatible sensor used in Case IH equipment—another CNH brand. The sensor shared the same part number and electrical specs, allowing a direct swap. The machine was back in service within a day, saving the customer from purchasing a new unit.
Another technician in rural Texas recalled modifying a mounting bracket to fit a slightly longer sensor body. By adjusting the bracket and recalibrating the control logic, he restored full functionality without compromising safety.
New Holland’s Parts Strategy and Global Impact
New Holland’s decision to consolidate parts support under CNH Industrial has streamlined logistics for newer models but left gaps for legacy machines. As of 2025, CNH supports over 1.5 million active machines globally, but parts availability for units older than 20 years is increasingly reliant on third-party vendors and salvage networks.
In 2023, CNH announced a digital archive initiative to improve legacy parts access, but implementation remains uneven across regions. Technicians in North America report better access than those in Southeast Asia or Eastern Europe, where distribution channels are more fragmented.
Conclusion
Finding obsolete New Holland parts, especially for telehandlers built through OEM partnerships, requires persistence, technical knowledge, and creative sourcing. While part number 85816651 may no longer be supported directly, understanding its function and specifications opens the door to safe and effective retrofits.
As equipment ages and manufacturers shift focus to newer platforms, the role of field technicians and independent suppliers becomes increasingly vital. Whether it's a boom sensor or a hydraulic valve, the solution often lies not in the catalog—but in the hands of those who know how to adapt, improvise, and keep machines moving.

It plays a critical role in safety interlocks, preventing boom movement under unsafe conditions or during startup diagnostics. If bypassed, the machine may operate temporarily, but risks violating safety protocols and damaging hydraulic components.
Terminology clarification:
- Proximity Switch: A sensor that detects the presence or position of an object without physical contact
- Safety Circuit: An electrical loop designed to prevent machine operation under unsafe conditions
- Bypass: A temporary override of a sensor or control, often used for diagnostics or emergency movement
When OEM parts are unavailable, technicians may consider retrofitting a compatible proximity switch. Key parameters to match include:
- Voltage rating (typically 12V DC)
- Sensing distance (usually 2–5 mm)
- Mounting thread size (often M12 or M18)
- Output type (PNP or NPN depending on control logic)
Best Practices for Sourcing Legacy Parts
To improve success when sourcing obsolete New Holland components:
- Search by part number across multiple platforms, including European agricultural suppliers
- Contact Manitou or Fermec directly if the machine was co-manufactured
- Inspect the original part for manufacturer markings, voltage labels, and thread specifications
- Use industrial automation catalogs to find proximity switches with matching specs
- Avoid bypassing safety circuits unless absolutely necessary and only for transport or diagnostics
