I figured it out finally the male qd was broken when I looked at it the plunger was off to one side. when I removed the old one the insides fell out and on to the didn't think that the qd could self destruct like that I have never even disconnected the qd before

I plowed snow the other night and everything worked the next day I went out to clean up and the bucket arms would not lift the plow blade. The bucket arm down pressure and bucket dump will lift the front end off of the ground and hold it. I tried switching the hoses around so that the lift/lower hoses were attached to the dump/curl ports on the control valve but the arm still wouldn't lift the other functions remained the same as before. The hoses disconnected reconnected normally nice smooth movement and clicked into place. I don't know a lot about hydraulics I think this would eliminate the valve control body as a source of my problem. Next I checked the hydraulic oil, the level is fine but appears a little milky. Last summer I broke a steel hydraulic line and I replaced the oil with a bargain brand that was supposed to meet jd specs. Could this be the source of my problem. Any one with any thoughts I would like to hear them
