Lynch Pins Coming Off

[MUDONTHETIRES]

Buy a set of 6 cheap keyed alike locks. Used instead of pins in equipment and trailer hitched, etc. imo

Read that from another poster, great idea. Thank you!

I have a few with the pin short enough that the circular keeper doesn’t stop on the pin, it passes it and the keeper lays flat against the implement. This lessens the chance of something getting behind it. It does make them more difficult for you to remove, but that what we are looking for right?

so cut or grind the end of them off a little.

I like that idea for the implement side, thank you!

Mine were doing that on my rear finish mower, found out that they had too much slack on the shaft between the post and the pin, I installed a spring and a washer to keep the linchpins from rolling sideways which was a lot easier for them to come off and I haven’t haven’t had another problem Since doing that, been good for about 10 years now with no lost pins. I can take a picture later of what I’m talking about if you would like.

Yes, a picture would be great. Thank you!

Way back when the Massey Ferguson 200 series were new they came with a locking linch pin. You had to squeeze he top so the bottom of the ring could be lifted to remove the pin. Some farmers cussed them because they did not squeeze them and actually bent the locking ring rendering them useless. I searched for them could not find them from Massey but did find the same pin used by JD pn AA23627. A quick search on the net finds the price at about $6.00. Don't know what other types cost but still cheaper than tearing up equipment.

I’ll check that out and thank you!

There's also the Rue Ring cotter pin

That’s interesting, thank you!

IMHO The best solution is to use a padlock and key or a combo lock. If using a key attach the key to your tractor key ring or handy area on the ROPS where the sticks and weeds cannot dislodge the key.

Third post on this, I like that! Thank you!

Are you talking about the lynch pin or the shear pin?

Talking about lynch pins.

 

[MUDONTHETIRES]

I assume it is the under growth unlatching the pins so would it be better to fit a suitable nut and bolt for this job. The inconvenience of fitting them is offset to the damage that could be done to the PTO shaft etc..

I’m debating on a nut and bolt vs a padlock now.

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 went to a different type of pin. See pics. Available in a lot of sizes

I've experienced the same thing. Seems like it's always doing pretty rough brush-hogging, nothing else. Zip ties and or mechanic's wife both are satisfactory fixes. I'm not patient enough to use bolts and lock nuts, though it's probably the absolute best fix.

Thank you, I’m picking some up for a couple of spots on my tractor.

I’m definitely trying several of these ideas and go through a process of elimination thing. Bolts and nuts on the front of lift arms because they won’t need removing and that’s one spot the lynch pin disappeared. Safety wire on some, etc…

I use flat washers on mine between the arm or link & the lock pin. I have noticed the arm or link works the lock pin out of the hole in the pin. It works for me, also a little squirt of Fluid Film on the pins seems to help. Cheers!!

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.

Picture is worth a thousand words! Please send
You will win the comment of the day!️

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.

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

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.

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.
