Gearbox Isolation Safety Switch for Ford New Holland and Massey Ferguson Tractors SKU: QT1833740

A failed gearbox isolation switch puts your family and equipment at serious risk—when this safety device malfunctions, your tractor can lurch forward unexpectedly during startup, potentially crushing someone or damaging equipment. This critical safety component ensures your transmission is in neutral before allowing the engine to start, protecting both you and your equipment from dangerous unexpected movement.

Why Genuine Safety Matters

• Prevents engine starting unless transmission is safely in neutral position
• Must be properly adjusted to function correctly on the transmission housing
• Built to endure thousands of cycles in harsh farm conditions
• Weather-sealed design resists moisture and contamination that plague electrical components

Safety first: Never bypass a faulty safety switch—these aren't inconveniences, they're proven lifesavers that prevent runaway tractors and crushing accidents. Our team at S&H Parts has the technical knowledge to help verify fitment for your specific model if you have questions.
