I have a L4600 I bought at auction with 260 hours. Running like a champ until last week while tilling, I lost all hydraulics. Steering was completely out. Took it into the dealer and was told the filter was clogged but had a lot of metal in it. They said they needed to explore to find where it's coming from. They dug into the PTO and all looks good. They want to put new fluid and a new filter (that's X2 at this point) and let me run it for awhile to see how it does. This is going to cost me $1700 and counting so far with no answers. Any help/advice is appreciated. I'm new to the tractor world by the way.
