The hydrulic will not work with me, but it work against me

I have a front loader and now a snow blade in the rear. I set the draft control leaver in horizontal position, and the rear blade lift only half way up.
If I set it in vertical position it don't move at all, but if i puch the leaver against the rear of the tractor it the blade startet to lift.

Going from front loader to scraper blade and scraper blade to front loader I have to pull the aux buttun when the lift or blade are on it's way up, to get the other to lift.
If I lift the loader or blade all the way up and then pull or push the aux button, then there are no movment from the blader or loader. And when this happens there are no sound from the hyd pump.

Sometimes it works like there never was any problems, but most of the time it it will act up. Didn't have this problem when dry testing the system before the snow came,
but now after only a short snow remove job. I think the problem has been there all the time, but it got more noticable when it had to perform

What could be my problem? I have a feeling it is the top plate with the aux funtion, but this don't explain the no sound from the pump.
It has new and plenty of oil

I also noticed that the main controll spring plunger would not move when I pushed the rocker...

Hello, Hei Winch... seems that you have a "watervast frozen" prob.?? få inn traktoren i varmt hus, gjerne rens og sjekk topp plata og fyll på new olje.

What grade of oil are you using?

Thanks for the answers. There should not be any problems with the cold, as there has been very mild outside.
I don't remember what oil I put in, I changed it this summer and researched this forum first, and put in the suggested oil.

It seems to need a adjustment, maybe change the stop pin, and change some o-ring.
But what is up with the main controll spring plunger, not wanting to move when I push the rocker?

Hi Tom, I still are thinking at the oilflow through your hyd.syst. - just befor you change oil it can happen that the thick mass of dirt is laying in the bottom of gearbox...If this has beeing in your system for a long period befor you got it changed...some of this thick mass mybee has been pack,ed behin d the valve.s and make stop in filter,s e.t.c. too. my point is that the hydr.syst. schould be cleened better than only change the oil once... or seldom?? -("Bottomvaste" -Bunnfall har stoppet mangen hydraulikk).
