    The plow needs some extra drop available to it so it can keep plowing when you go over a hill. Otherwise it would leave snow on the ground.

    ok but I mean when i want to take the plow off or put it on the ram is so hard to push down it takes 2 people to push the ram down so there is slack in the chain to move the frame around to take it off and put it on. I just dont know how its so hard with 2 people to move it down to put extra slack in the chain but like u said its normal so i guess its ok thanks a lot for everything thanks mckenzie.

    It isn't normal but over time you get junk in there and some small pitts in the chrome. Is the cylinder smooth? Is the packing nut to tight? If you replace the cylinder and packing and tighten it to proper specs it will slide down with one person smoothly. I had one that was so bad that even two people couldn't get it down.

    There must be something wrong. One guy can push ours down with a bit of force. Make sure you leave your controller on, and the down button (or stick down) is the last movement you make on the controller before you go out and push down on the cylinder.

    I had the cylinders redone on my MVP plow two years ago and immediately noticed how stiff it was to "retract" the lift cylinder to remove slack from the chain, initally i hammered the lift arm, did'nt like that so did a stand up and pounch on it, did'nt like that when things were slick and switched over to a kick the chain method, and now after two years it's just loose enough i can put constant pressure on the chain by pulling on it, strong mind you, but it'll come down.

    Will admit the plow works muuch better with the rebuilt cylinders:) so the trade off of being a lil stiff is worth it.

    I had this happen with a plow that sat around for a long time. You can hang the front of the truck off of something (curb, downhill...) to get the plow low enough to bring the ram all the way down. Do it a few times and it might losen up. Worked for me.

    As far as loosening it won't hurt to try. It is normal for a little fluid to be on the shaft but not so much that it starts to run down the front of the pump. You can always tighten it back up. You could also replace the packing. If you do lube it up when you reassemble.
