Proper Uni-Mount Hitch Pin Orientation?

    I recently started plowing with a 7'-6" straight poly Uni-Mount, using Ultra-Mount truck-side brackets and the appropriate conversion assembly.

    The first time I went out, the cotter pin somehow came out of the main hitch pin on the drivers side, and the main hitch pin eventually worked itself out of place. I noticed "slop" in the plow movements, investigated, and was able to recover the hitch pin, but the cotter pin was long gone.

    Everything held together on the second trip, but when I took the plow off my truck today... I noticed that the new cotter pin in the drivers side hitch pin is twisted apart, to the point where it could've easily fallen out and made me lose the main hitch pin again.

    Any thoughts on why this keeps happening? Am I somehow installing the cotter pin improperly? Is there a certain orientation that it has to be installed?

    I can take a picture of the cotter pin if necessary but, basically, imagine forcing one apart until it's shaped like a "V" and no longer holds itself in place. That's what it looks like.

    Thanks in advance!

    Not sure on why but spend a little extra money and get the hitch pins that require 2 pins. Also do not use a standard cotter pin they make a funky looking pin called a hair pin cotter that I have never lost.

    Get a few pics of how you have it installed. I have 2 and have never had any issues with either doing this

    ^ Ditto.

    I run mine with the handle out, pin in, never an issue.

    yea, lets see some pics. only thing I can think of is your putting the 1"hair pin on the outside of the bracket instead of the inside
