Hi, I'm a long time reader but never posted before. I have a B3030HSDCC a little over a year now and just today learned something. My nephew was using it today and when he parked it in the shed he removed the key from the ignition by mistake and when he replaced it he put the key for the doors in the ignition. Then when I came there to move it the key would turn the switch but the tractor would not crank. After I spent about 5 minutes looking around for a problem I saw the wrong key was in the switch. After I put the correct key in the ignition it started right up. I thought I'd post this as a FYI just in case this happens to someone else.
