2555 HST from bad to worse

Thought I had a large problem before (that other's graciously helped with), but that's child's play compared to today's development. I was taking my tractor to hook up a box blade (about a mile). I put it into load sensing so I wouldn't bog on a slight incline, and noticed it was surging, not staying steady like it used to when I'd use it for loader work. Took it out of load sensing and continued along not beginning much thought. At my destination, I backed up to connect box blade, and was annoyed that I missed by an inch, so i walked over to the cab, as I was going to inch it forward. That's when I got REALLY annoyed. Hydraulic fluid was gushing from under the tractor. At first I was terrified thinking it was oil, but it wasn't. It's hydraulic fluid that shoots out under pressure when the tractor runs. Appears to be spraying out somewhere under the cab on the center-left. Appears in the general vicinity of the filter that's under the cab. Filter does not appear loose or cracked. Has anyone had experience with this?
Thanks in advance

Yes I have had experience with hydraulic oil gushing from under a tractor. I always found the best thing to do was find the leak and fix it, whether that be replacing a hose, gasket or whatever.

One time when I was younger, I started up an older Chevy van when it was about -15F. I had the cover off the engine inside the cabin and saw engine oil cascading down the outside of the oil filter. The oil was so cold that it blew by the gasket on the oil filter. Yes, the filter was tight.

Is it possible that something similar happened to your tractor at startup and you simply discovered it when you got out of the cab? That would explain the surging when you tried to climb the incline.

You could have run over something and snagged/bumped/tore something up underneath... is my first thought. The bad part is the weather.... today is our ' warm ' day, maybe stay south of zero the next few days.... There are several filters, wires, and lots of hyd lines running underneath these tractors. Hyd everything... Good luck, Jerry....!!!! [ stay warm...!!! ] I am going to do my drive/road/mail boxes today whilst it is still a balmy 10-11 degrees...

Funny reading this as the exact thing happened to me a few days ago with my Duramax. Severe cold and hadn't driven it for a couple days and didn't have it plugged in. Decided to see if it would start. Fired up and as I got out to go in the shop I look at my truck and see a stream of oil the size of my finger flowing! Shut it off quick and crawled under and couldn't find anything. Started it back up and nothing! Took it to my friends shop and put it on the lift and all we could figure was it blew by the gasket on the oil filter. So we changed the oil and put on a new filter.

Sorry to highjack the thread but found it funny reading this.
