I was getting the runaround on my machine also. I had to have a field tech come out for a calibration that required the Bobcat software. That's how I ended up getting mine. My machine was not locked and I actually found the owner code written on a window.I have been getting the run around when I have been calling the dealer and repair shops
I don't know if New Holland has a master code or not but try to get it if you can. On a Bobcat it will override all other codes and you can't accidentally change it.Thank you. One dealer about 3 hours away said I could drag it on a trailer and take it to them. I guess that's a last resort.
