I figured the hyd switch wasn't the problem. It doesn't matter how far you extend it, it won't come back, everything seems to be in line, and when extended if you push the button to extend you can hear the engine rpm change a bit, but not when you are trying to get it back. Once it comes back it seems to work ok after that. We don't use it continuasly very often, we are a trash service and we use it to pack the trash into a trailer, and when unloading a truck we use the extendahoe to push the trash out of the way. We do have a guy who packs the trash with the hoe out, I assume that can't be good on it. The problem started about a month ago, and as I said it seems to be getting worse, I would hate for it to get stuck all the way out.
