    Cotter (traditional split) pin for pins between 3ph and iMatch frame?

    Almost every movable connection on my tractor is retained with either a Lynch pin, a hairpin or a bowtie cotter. The one exception is the connection between the 3ph arms and the iMatch frame. Those are old style split cotters. When my hydraulic top link arrives, I'll obviously be removing at least the top pin. Not a big fan of the sharp edges on split cotters, but not sure there's a low profile alternative for retaining pins that don't need to be removed on a regular basis.

    Any thoughts or suggestions beyond just replacing them with the same?

    I use lynch pins in mine and haven't had any issues.

    I still take mine off from time to time for the post hole digger and tiller, so the lynch pins are handy for me.

    I have always routinely replace cotter pins and R-clips with lynch pins. I drill out the hole if necessary.

    There are smaller lynch pins that should fit just fine.

    My fixed hook I Match has them...I forget if it came with them. I keep a few dozen of all the small sizes on hand for the mini ex buckets. I routinely lose them when working in the brush or with the narrow bucket.

    Cotter (traditional split) pin for pins between 3ph and iMatch frame?

    I replaced the cotter pins with circle lynch pin, not fan of them. Pliers are need to install and replace properly. I use the lynch pin that are found on other places on my 1026r. Always keep several sizes on hand from tsc.

    I have one of the 3 tractors (all with imatch) set up with lynch pins, in order to remove the imatch w/out tools. This is for use with a 2 bottom plow when imatch is removed.

    Not in the majority

    If you aren't going to be taking the I Match off, I'd go back with the cotter pins. As others have said, lynch pins can get popped loose and if that happens you've got a 2 ph and some unfortunate things can happen.

    If you are going to be taking it on and off, get the strongest lynch pins or even better get a locking pin. These are an oversize version of a safety pin.

    You can also use a bolt and self locking nut. Back when we use a plow the lower lift pins had a cupped shield and we used a bolt and nut because really bad things would happen if one side came loose and if the plow was set deep, the lift arms would get hit with corn stubble.

    If there is a concern about the lynch pin being removed by corn stubble, or branches,,
    and you do not like the sharp edges on a cotter pin,,,

    how about a suitably sized bolt with two nuts??

    "Jam" the two nuts together on the bolt, and the bolt will not come out until someone puts a wrench to the assembly,,,
    Some of the tractors include JD 4105, JD 855, JD 650,,,, and,,, the IH 584 4WD
    My favorite attachment is the homemade landplane,,, EVERYONE needs one of those!!

    About 40 years ago a friend used a large cotter pin on an old power takeoff (PTO) and lost half his hand when a couple of days later he fell while the PTO was still spinning . . . I was helping him with the hay and drove him minus lots of blood and three fingers . . . he may have had a broken hand if he had used a lynch pin rather than a cotter pin

    I have "zero tolerance' for cotter pins since then.

    I gave my grandson a very old red wagon about 20 years ago . . . my daughter laughed saw she saw that I had replaced the cotter pins (5) with lynch pins
