It can be pricey to replace a thermostat on the John Deere 850, 855, 644B, or really any equipment. Thats why we sell new high quality thermostats direct at often lower prices than even a used John Deere thermostat!
Price is just one part of the equation though- quality matters too. We don't want you replacing your thermostat more than you need to, which is why we back our parts with an industry leading warranty. Even if your 850, 855, or 644B is not your main piece of equipment, TractorJoe knows that having it up and running is always important.
It doesn't matter if you're installing our thermostat in your John Deere industrial/construction machine, John Deere tractor, or something else, we'll be here for you. Our staff knows a lot about John Deere equipment, and our Q and A community is there for any other questions you may have.
