    Default MF Plough

    Recently I bought an MF 345 reset plough at an auction. The name plate is gone off it so I have no idea what the serial # is, but it has hydraulic rams on each share.

    When I hooked it up to the tractor, and tried to use it, the blades kick up as soon as they start to bite into the dirt - seems like there is no pressure in the hydraulics on the plough. (the tractor hydraulics are fine, I use them all the time for other attachments)

    There is a thing like a small air tank sits on top of the plough, with a gauge on it, and a line from that to the hydraulic take-off on the back of the tractor. There is some faded lettering, something like " use dry n.....something only." The gauge is at 0. When I first hooked it up, there was creamy yellow foam came oozing out of the tank.

    Anybody know what I have, or tell me what I can do to fix?

    I believe that's an accumulator. (Probably says "use dry nitrogen")
    There are three kinds of men;
    1.) The ones that learn by reading
    2.) The few who learn by observation
    3.) The rest of them have to pee on the electric fence for themselves.

    OK, what does it accumulate? and any thoughts as to how I get this plough to work properly?
    Should there be something in the accumulator that acts somehow on the plough hydraulics to keep the shares working in the dirt, or do I need to add weight behind?

    I would start with taking some good pictures, that should help to ID the thing. Try to get a manual or visit the local MF Dealer and see if they can tell you something about the plow. If indeed that is a accumulator and it does take dry nitrogen there will be some tools you'll need to recharge the thing. If it's not leaking, that is. You'll need the pressure guage/regulator and a bottle of dry nitrogen to recharge it. It might be a project to load up and take to a good hydraulics shop to get recharged. bjr

    Google "accumulator" regarding hydraulics. It serves as sort of a "shock absorber reservoir" on that plow.
