hydraulics freezing up

[just plain bob]

I use my L3400 365 days a year. In the winter, the hydraulics gel making the steering a work out and the front end loader non existent. I've been told that there is water in the lines. I change the fluid annually but still have the same problem. Any suggestions?
thanks

Have you considered moving farther SOUTH? Do you park you tractor outside? Is hyd oil reservoir breather plugged? Have you considered using SUDT?

I am not saying this is the cause of your problem, but I will say that when I did the 50 hour on my L3200, I changed the hydro and filters out and refilled it with SUDT2 and wow what a difference. Thy hydro works much better when cold. Sounds interesting. I assume you have been changing the filters when servicing the machine-

Also, I am not familiar with that machine- does it have a screen on the pickup tube for the hyd pump? That is something that is easy to miss cleaning..

moving south is in the future but for now, I park it in an unheated barn at night, I don't remember what the last oil I bought was but the kubota dealer here said it was the best - it was the most expensive too. I did a quick google on the hyd oil res breather and still have no idea on what you are asking?
thanks

always change the filters

Could be a bad pump seal or something else in the system causing pressure loss.
I would get a pressure gauge and check the system pressure.
