    I have a mm1 7-1/2' Fisher plow. I converted it to the three plug system in order to get it to mate up with my 04' Ford pickup.
    I busted a hydraulic line and have lost all the fliud. I don't have an owner's manual. Can anyone explain the procedure for refilling the system?

    I would fill it up through the fill plug. Til it is at the top of the hole. Pick the plow up left right down then let it sit a while. Re check fluid level. careful removing even fill plug sometimes there is pressure in the rez. And repeat process.
