678 tale gate won’t stay locked.

samedi 23 mai 2020

We have a 678 New Holland baler. Last week we used it one day without issue but the next day we had issues with the tail gate staying closed. Changed tractors, no change. 
Today I serviced the baler and closed and locked the tail gate. I walked away for 20 minutes with tractor not running and then I noticed the latches had released yet the hoses attached to the tractor were still under pressure. 
 

I've never seen this issue before but my theory is one of the hydraulic lift cylinders has a seal inside that failed. Is my thinking correct or is there another issue causing this?
