Is this a genuine original part?

This is a premium quality aftermarket replacement part supplied by 4Drive, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.

How do I know if it is compatible with my tractor?

We recommend checking your current glow plug's stamping. If it shows "Y1021J" or matches any of the OEM numbers above (like John Deere CH19846), it is the correct fit.

What happens if the resistance (Ohm) is different?

A correct resistance of ~0.9 Ohm is critical for 11V systems. Deviations can lead to poor starting or burnt-out plugs. Our Y1021J is precision-tested to match the factory specifications.
