Good afternoon. I have a JD 850 around 89 that I just solved a problem with and have another maybe related or cause by.
My draft control was pushed accidentally to the limit and caused pump squealing. It forced hydraulic fluid into the backhoe as to take over and I then shut machine down...
I have JD 850 mini tractor with backhoe and loader. Recently the backhoe jammed up and fluid started oozing out of seals everywhere and pump starting squealing. It was like too much hydraulic fluid was driven into the controls and overwhelmed them.
Disconnected the backhoe and tried the loader...
