Question Water in the hydraulic lines?

I bought a Curtis Sno-Pro 3000 last winter used. I flushed the hydraulic lines and refilled it with Curtis plow hydraulic oil last winter as well. When I took the plow out of the garage on friday for our little snowstorm, everything worked fine. As soon as the snow and temps fell in the 20's, the plow hydraulics wouldn't budge. The pump was running but I was getting no plow movement. The temps warmed up yesterday and I tried the plow and it works perfectly. Is it safe to assume there is water making it's way into the hydraulic lines and it didn't work because the water froze and blocked the lines? If so, does anyone know how the water might be getting in the lines so this won't happen again after I flush the lines?

Thanks!

The plow is kept in my insulated garage year-round when not in use, so I assume it isn't the first potential problem you mentioned.

Look at the rams for wear, damage, and them the seals where the rams enter the piston. Most pistons rebuildable
