I have a TC29 and the Hydraulics SCREAM in cold weather. Today I was plowing snow and a tube flared fitting failed on me. I need to replace the hydraulic tube now. I think its because the fluid is too thick. The outdoor temp was 17�F. I see all kinds of heavy equipment sitting out in the cold and they use it to plow parking lots etc. So why is my hydraulic system doing this? The fluid that leaked onto the drive way started to turn to gel in about 30 secounds. You just can not suck this thick fluid through the filter and it starves the pump causing the winning. This is my opinion anyway. This fluid is supposed to be rated for -13�F. I call BS!
If you change the filter yes it will fix it. However, it will come back. If the weather gets to 40 there is no whinning at all.
I'm going to buy a few different quarts of this hydraulic fluid and let them sit out over night. then pour them in the morning and compare which brand is the most fluid. I'm really tired of this whinning and I do think I'm damaging the hydraulics. The pressure is to high for the system when the fluid is a gel. That's why my line failed today.

I look forward to any comments anyone has on this.

Thank you all for your feedback. Happy plowing!
