Can someone help? The plow will raise but is slow, if the plow is against a snowbank it won`t raise at all unless I back out, it acts like it`s low on oil but is not. The plow will also creep down slowly. I have changed the o rings on all the valves,none of the valves are sticking, I also changed the packing cup and seals.The plow angles left and right with no problem.

probably a bad motor.

Weak motor or weak pump. When trying to lift plow against a snow bank, have someone listen to see if the motor stops or is still running.
Motor stops, weak motor.
Motor keeps running even after plow stops raising, weak pump.

I'm having the same problem, and its getting worse. It drops fine but is slow going up and to the right side.

My sense is that theres not enough battery power.

Mine does the same with a new motor and rebuilt pump. Im convinced it really needs a dual setup, but it does ok with a single. Just a little slow.

I have dual battires. The pump just does not have the power to pick up the plow.

You're just trying to be difficult, aren't you Gene. lol

I dont know then. Maybe it is a weak motor. The one I have is brand new so, I dunno.

Its not terribly slow but slower than I recall it being.

Check all your grounds. I had the same problem and I just checked the grounds and cleaned them and it made a big deferents.

The one we have at work does the same thing in the early morning or for the first few times of use then it slowly starts to work fine and we keep it in a heated shed every night. cleaned the pump and changed fluid still no difference.

sounds to me like the pressure relief valve is set kindof "light". try turning it clockwise a 1/2 turn and see if that helps.
and as far as it creeping down, it could still be the A valve. I was working on an E-60 the other day that was doing the same thing, and even though the poppet inside the valve moved freely and looked okay, it was still letting a little fluid move past it.

I would also check the plunger seal at the bottom of the lift piston my was almost gone and doing the exact same thing as yours. It takes about an hour to put new seals in might be worth a shot. Also if your fluid is black it's a good sign the plunger is gone.
