    plow gets stuck when all the way angled and vapor locks. I chaged hoses, hose fittings and couplers.

    If your couplers are hard to uncouple then you have a bad coupler.

    Check to see if the shaft of the C valve is swollen

    Not even gonna touch that one. :D

    Would also be helpful to know WHICH direction the blade hangs up in.

    I am having the same problem, but why would it still do it with a backup pump?

    As I already mentioned previously in your case, a bad coupler on the plow side or an over travel issue. Or a bad C valve on both pumps (saw that one many times). A couple temporary stops on the sector can help rule out an over travel condition.

    My CP-8 would do that after it sat a while between storms. Didn't matter what pump unit was on the truck. Changed couplers, hoses still would do this. These were brand new rams too. I ended up fixing the problem by backing off the gland nuts on the rams a 1/4 of a turn. They were way too tight, haven't had the problem since. No leaks whatsoever. Might be your problem?

    I had this problem at the start of the season. I have the toggle switches for my up and down and then another one for the left and right. I had a wire that fell off the left right switch over the summer and was not letting it get the full voltage to the pump. It was not a fun job to find and it took over a week to find.

    You could have a bent Aframe too it brings the whole thing out of line and then it will hang up when u get to one side
