    I went to take my plow off today, which I've done numerous times before, and can't get the chain lift pushed down any to retract the lift cylinder. I put the plow in float, but not having any luck. One chain is very tight, while the other is loose. Any help is appreciated. I need it off asap.

    No. I just cant get slack in the chains to take the plow off. I've always been able to put it in float and push down on the lift cylinder and it was a piece of cake.

    Cutting edge could be worn down,put something under it and try again.

    I'll try it but do you think it would keep me from being able to push the chain lift down? It's always went down easy before.

    Does it go up and down like normal with the control?

    Yes. One chain is tight, other one with slack.

    I'm confused about how one chain could be tight and the other one is loose. Are you trying to take it off on a level surface? Is the chain caught on something? How much of the lift cylinder is still showing when it's as low as you can get it?

    I usually have to twist the chains by hand to get the lift cylinder to collapse. Mine won't go down by pushing the lift arm.

    My lift cylender won't go down all the way either. I put 4x4 timbers under each end of the plow and that gives me enough slack to work the head gear.

    Take a picture of the lift cylinder for us. There have been issues with the lift cylinders in the past. How old is the plow?

    I was too. When I hooked it up this yr, one side was tight and one loose. Will that cause any problems? Anyways, to catch up on a couple other posts, there is still plenty of room in the cylinder to be pushed down to loosen the chains. The one chain is too tight to twist to get the cylinder down. Where do I check the fluid for air lock? Sorry, only been plowing 3 yrs but this hasnt happened before. The plow is only 3yrs old as well. In good shape.

    Put a jack stand on your cutting edge and lower it as far as you can. Then take the chain off and re set it.

    You can also just crank you jack to lift your A-frame up enough to get more slack to allow a link or two out.

    By twisting the chains, I take one chain in one hand and the other chain in my opposite hand (obviously), then I cross the chains pushing down at the same time. It creates a scissor type motion that gives enough pull to move the cylinder.

    Had a friend who couldn't get slack on his MD75 (know its different); suggested the usual float, push cyl down... wouldn't go down.

    Had him try lowering plow when overhanging a lower elevation (off edge of raised pad). THis allowed cylinder to "break through" a slight burr that normal float spot built up. Back on level surface, he could then push the cyl down when in float to slack chains.

    Easy to try, might help. Good luck!

    If your packing nut is too tight, it wont push down very easy..
    I grab one chain in the middle and pull hard outward. More leverage that way.
