That’s the million dollar question though. He puts the old oil back in and it works fine, like before the oil change. So the question is…what oil did he use which caused the issue? He may never admit…

It shouldn't, he's got something else going on there.I've been running the recommended fluid with no issues. I just don't see how using the recommended fluid could possibly cause the issue shown in these images.
The GC 1705 and GC 1715 are NOT factory backhoe.... The GC 1710 and GC 1720 ARE factory backhoe... The real difference is the GC 1705 and GC1710 are like 22HP and the GC 1715 and GC1720 are 25HP..Is that a factory backhoe tractor or non-backhoe?
