bucket won't lift

[refueler]

I plowed snow the other night and everything worked right, but when I went out the next day to clean up the bucket wouldn't raise it would put down pressure and dump and curl the bucket. When you try to raise the bucket you hear the relief valve lift. I tried reversing the hoses lift lower hoses were swapped to the dump and curl. This made no difference the bucket won't lift. I looked at the hydraulic oil and it looks milky. Last summer I broke a line and I put a bargain oil the met jd specs so I'm going to use the rest of the bargain oil to flush the system clean the screen and change the filter and replace the oil with jd oil. If anyone has any suggestions I would appreciate it.

Sounds like you have an ice problem in your cylinder-s try heating them up NOT with a torch.

How cold is it? Milky fluid indicates water contamination, if its below freezing then the water in the oil is possibly frozen.
