6210 "Frozen" hydraulics?

[Conn]

Coldest morning of the year thus far. Let the tractor warm up for about 30 minutes before venturing out to feed and the hay spear wouldn't "curl". Loader will work up and down but no curl function and I can't move the levers for the rear SCVs either.

All three of the "stuck" levers have the same feel to them.

I'm thinking there has to be some condensation/water build up somewhere in my rear valves?

They all worked when I parked it yesterday morning after feeding.

Any thoughts?

The hydraulic oil doesn't have a "milky" look to it.

In looking at the parts break down it appears that your SCV's are all actuated via push/push Bowden cables. There is a chance that these have become stiff in the cold and won't move properly. Seen this happen with the shift cables also. Can you get the tractor is warmer building and see if the problem goes away.
It is not a hydraulic issue since the loader moves fine and you did not report any unusual noise.

I agree on the frozen cable. Same thing happened on my Kubota M4900 a couple of days ago. I let temp get above freezing and everything worked fine.

Yep. Went outside at noon and everything worked again. Probably time to lube/or replace the cables!

Since I hate seeing threads with "problems" and no "solutions", I'll provide an update...LOL.

Replaced the cable and while doing so, a small amount of water came out of the cable housing at the rear of the tractor where it mounts to the valves. Could have avoided replacing the cable by checking for water first, but was already in too deep. It went the rest of the winter without a problem.
