    I have been having a problem with frozen hydro fluid. Yesterday I changed the fluid. This morning the plow was frozen again. How do you get all the water out of the system? Thanks

    Did you drain the fluid out of the angle rams?

    I put the plow in "V" position and pushed the lift ram all the way down.

    That's not getting all the fluid out of the rams

    Remove the hoses from the pump that goto the rams. Lift plow with jack. Place hoses in a suitable container above the bottom. Pull the wings out all the way and then push all the way in. A few times with both wings. Then you can take the lift ram hose off and pull up and push dwn and you'll get a little bit out of it too. That should get most of the fluid out

    A Tea spoon of isopropyl alcohol will help. Best bet is to use low temp hydraulic fluid, like fisher fluid.

    I use the low temp fluid but have wondered about adding a bit of dry gas. Do you add it when temps get brutally low?

    I use seafoam trans tune, a couple ounces when I change the fluid. The first storm last weekend was the first time I had any issues with moisture. My fault for not getting the fluid changed before the first use. Dumped a few ounces of transtune in, worked up and down a couple times and it worked fine to finish out plowing.
