We are having trouble with the baler door not staying close. We had the lock out valve re-built but the guy said their was really not much wrong just replaced a few things. Anyone have any ideas as to what else it could be?
 
Had the same problem on my NH850 and I bet the problem is the cylinder one or both are leaking in side. Rebuild them bot hat once or you will find the problem comes back sooner then latter
 
Seems to me that lockout valve has an adjustment on it? If so, have you tried to adjust it at all? If not, I may be thinking of a different New Holland baler I have. I do remember having to adjust that once. Otherwise your tractor remote valve can leak and cause this too. The lockout valve is supposed to prevent this, but will to a limit. Swap hoses in the remotes, or use a different set of remotes, or try a different tractor and see if it goes away. If you haven't done all of the above already. Otherwise I'm with old. Good luck.
 
The limit does very little to help with that problem. Back when I had that problem I tried every thing you talk about and it ended up being one of the cylinders. I rebuilt it and in less then 10 bales the other cylinder went bad
