Lynch Pins Coming Off

[MUDONTHETIRES]

I only lose them where the lift arms attach to the tractor and only when I use my neighbors heavy duty 5ft brush hog, so I went with bolt and lock nut that someone else mentioned in another post. I tried the black pins from tsc but they came off too.

I’m going to use bolts and nuts on the front of the lift arms. The right front lift arms has fell off twice so hopefully this will eliminate any more issues. Thank you!

Before applying the springs the pins would rotate on their axis which made it very easy for them to come off now they have tension and stay flat or horizontal and have never lost another pin sence, hope this makes sense.

Thank you for the pictures! I’m in the process of choosing between two finish mowers and this will work!

I learned a lot from this thread.

First time i used my snow plow, with caster wheels setup like the op has, i popped the same kind of lynch pin off one of them. I wasn't too happy that it was hidden in the road someplace. I used a piece of wire as an interim fix. Fortunately my wife found the pin in the spring while walking, off to the side of the road.

Simple, quick, inexpensive, but don't pull an OMG where's the key !

Perfect idea!!!

For the pins that are not removed often, just put in a 1/4" bolt with a lock nut in place of the lynch pins.
Having a quick hitch like the iMatch facilitates this switch to bolts, as well as those lynch pins used to secure the arms to the tractor pivot pins.
I lost one once, and almost cost me a broken casting.

Doing that on the front of the lift arms, thank you!

Some questions about how these come out. I've lost several over the years and believe one way is branches are springing up and grabbing the ring, just guessing but tree limbs have created havoc for me in several different ways. Some are stiff as metal and some are springy and seem unbreakable and can slip in almost any where and grab and puncture and pull "stuff". My 2 cents.
I keep planning on getting some hardened steel bolts with nuts the right size and bolting some of my attaching points down or in.

I agree 100%. Either slack in the lift arms, branches, design of tractor or something has caused four pins to come out in the last five times I’ve used it.

There are several posts about this but not many recently so a new day means new ideas. When I brush hog a different lynch pin falls off nearly every time. I've brush hogged five times in the last two months and have lost four lynch pins.

Facts: I do have a lot of overgrown weeds and saplings and I do use the HD black lynch pins.

My question is how do I keep them from coming off? I don't care about losing them so much as I do about tearing up my equipment. Chaining them to somewhere on the tractor just keeps me from losing the pin but it doesn't stop the inevitable damage from the pin coming out. Is there a better more secure pin out there other than a bolt and nut? Duct tape? Key rings? Thanks in advance for any and all suggestions.

I find using a quick hitch where I don't need to use lynch pins solved the problem, but not all my equipment can use the the quick hitch, plus I have to use an extender on the PTO shaft. Try closing the ring on the lynch pin with the sloped side away from center. They seem to not open up and fall out that way.
