FAQ — Frequently Asked Questions

What is the purpose of an engine speed sensor on a John Deere machine?

It transmits engine RPM information to the system that uses it on the machine. When it becomes irregular, the RPM display or related engine information may be disrupted. To replace it correctly, comparing it to a reference is the most reliable method.

How can I verify that this sensor is the right fit for my machine?

Start by comparing the part numbers associated with this item: RE519144, RE508195, YZ150115, RE71121, RE63919, and RE43511. Next, check the exact model designation of the machine and any suffixes, such as SE, S, PR, T, RT, or N, which may indicate different configurations.

Is this sensor compatible with the John Deere 6120, 7610, and 8210T?

Yes, these three models are among the applications listed for this part number. The 6120 is part of the 6020 series, the 7610 is part of the 7010 series, and the 8210T is part of the 8010T series. Before ordering, however, please note the part number on the sensor you removed.

Is this part number reserved for John Deere tractors?

No, it is not limited to tractors. The listed applications also include John Deere combines from the C, CTS, S, STS, T, W, and Z series, as well as forage harvesters depending on the listed models. Identification must therefore be done on a machine-by-machine basis.
