John Deere Tractor Will Start But Not Move

[Foor]

I have a John Deere tractor that will start but not move. This is the coldest I've ever tried running it in. Normally, it works perfectly. Is the temperature the likely cause?

I don't think the temperature is the issue since you were able to get it to start. Something like that happened to me and it was the transmission, unfortunately.
