    Little help with MMM arms staying locked up

    Fixin to head to our property and I dropped the 60D deck. Only need is for the loader and box blade.
    I asked the ole boy I bought this thing from how you can operate the 3 point without the mower deck going up and down, and I thought he said to place the height selector in "LOCK". I "think" I remember it working properly as he said.

    I just dropped the deck and put it in the lock position and the linkage for the mower deck goes up and down with the 3 point arms. ??

    I looked under there and can't figger out how moving that selector knob does anything to keep the linkage arms held in the UP position.

    I finally just put the thing at the highest cutting height to prevent the least amount of drop.
    What am I missing or not understanding?

    Going back outside to get my trailer hooked up and box blade attached. Will check later for any helpful info.
    If I can't get that linkage to stay up under the tractor I'll end up plowing some $hit with it.

    Appreciate any help

    I've found out over the years of having a series 1 26 and 25r , what is shown as the Locked or install or other settings are maybe a tad off. After lifting to highest position move lever either to the left or r on tab and it should stay in the locked position.


    Yes after moving to the locked position it still may drop a little.

    Are you lifting the 3 point before you go to the lock position? In other words, 1>Remove the deck, 2>Raise the three point, 3>Set to lock position.

    Thanks Gene. I got to get me a Manual for this rig.

    I ain't sure, but it feels like you can crank that knob clockwise from lowest setting to H or G, and if you want to get to Install you have to go the other direction from lowest height to Install and Lock. I think.....

    The knob lined up with "Lock" ain't keeping the mower linkage arms from going up and down.
    In fact it don't keep them from going down and up either.

    I'm assuming you have an independent mower lift. If you don't, the deck moves with the 3 point and the 3 point moves with the deck (that ain't broke that's how it works). I don't have independent so can't help you with this one.

    Look up under the left (drivers side) floor board at the stepped circle thing a bob (cutting height knob) turn it so the arm hits it at the highest point. At that setting my deck drops maybe a half inch then stays there as the 3pt continue to drop.

    The gold colored upside-down spiral staircase looking thing is the 'stepped cam', it is what rotates when you turn the knob. The picture shows it in the locked position. The black lever is resting against the very bottom of the stepped cam. This is what keeps the arms from dropping.

    My deck height control is not independent from the 3 point, no hydraulics.

    I have the stepped "gear" thing figured out on how it relates to the selector knob, but can't see how it prevents the deck linkage arms from dropping.
    The photo helps, thanks.
    When I get off work I'll take another look.

    But, isn't the "LOCK" position supposed to prevent the arms from dropping?
    My deck disconnects and connects with no problems.
