So many issues with these later model GC's after the 1705/10/15/20's!
Junk b/h valve thx to bad castings, junk pressure relief valve which causes hydro whine, junk loader valve which leaks, junk backhoe controls enclosure which breaks off, and now this thing with the sight glass.
Dudes on facebook are bitching about having to take theirs back numerous times for warranty repairs. WTF Agco? It's like their new business model is to build a cut-corners tractor.
I'm sure glad I have the old GC1710. I've had literally zero issues with this thing, and I haven't babied it.
