I purchased a 2388 that has the AFS Moisture Sensor on the grain elevator (prt # 364842A2), the only problem is that the screen was stolen in the cab. The combine was purchased from a JD guy and he didn't know anything about the monitor. I talked to my local dealership and they said it would cost me around $4700. I believe it was for a 600??? I'd like to have something, but I really don't want to spend that kind of money. Any ideas or help would be appreciated.
