Combines afs on 2388

It depends on what you have the monitor set to use. To use the satellite speed you need to have the vtg string on in the receiver. I use the reciever beacon with ground speed as a backup if I loose signal. Calibrated ground speed from the wheel sensor works fine unless you get into muddy ground and have wheel slipeage.

If you really need accurate ground speed with the Yield Monitor_AFS system, you can install a True Ground Speed sensor(radar unit) on the combine that will measure actual ground speed. You will have to program the AFS system that it has a radar unit.
