Thanks. I will try that!

I haven't cleaned the screen yet, maybe that should be my next step?

Might be a good idea. Here's where the hydraulic filter is located on the 2wd version, under a triagular plate at the bottom front of the transmission.

I hope your filter looks better than mine did. A too-large o-ring had been forced in there. It was compressed so hard that it welded the filter into the housing. After a lot of tugging the filter came out in pieces. A new 'strainer' (filter) and the proper o-ring cost about $60.

Very helpful, thank you!

K, I drained the hydraulic fluid and cleaned the screen. The strange thing is that the hydraulic fluid was real milky, apparently has water in the system. That explains why a couple of my loader lines split, most likely 'froze' like water lines. I have refilled and the fluid is looking a little milky again, will most likely have to drain and change again. It seems like the more I work the hydraulics the better they get, however they are still not 100%. They start off great and worsen as the tractor runs. I still haven't had a chance for photo's, I won't bother with the 'rod' that moves back and forth out of the casing near the shifter until I can show you a picture of what I am referring to. So, any more ideas for me?

I wonder if the water will settle out of the hydraulic fluid if you drain it and set it aside in a barrel. Anybody know?

The fluid I drained 4 days ago has not separated yet...

one more thing, my Yanmar is the 4x4 version. Does anyone know if the front axle shares fluid with the transmission and hydraulic system. This tractor sat in a dry pond (that wasn't always dry depending on the rainy season) and water from the front axle was one of my theories as to how the water made it in.

The front axle lubricant is separate from thentransmission and hydraulic fluid. The drop box that powers the driveshaft shares fluid with the transmission.

I don't think the water settles out once it has been emulsified. I expect there are emulsifying agents in the lubricant to keep that from happening. Old hydraulic fluid in some of my grandfathers implements, that had not been operated in a decade or more were still yellow-milky when I drained them. I imagine careful heating could evaporate the water while leaving behind the oil, though.
