3-Point Hitch lynch pin help

[Gary Fowler]

It is hard for me to imagine a pin coming out snow blowing as there shouldnt be anything to snag them. Make a few like GWDixon show with washer first then slip the pin thru and if it comes loose then it must be breaking in which case something is not right and causing the lift arms to pull excessively on the pin. Maybe try putting in a grade 8 bolt with either a double lock nut or nyloc nut with a washer on the lift pin before the bolt. I have lost a few bush hogging and broken some with the box blade but only after bending the lift pin.
Look for the cause of failure rather than constant pin replacement unless you were putting them in wrong which I doubt unless you are flipping the bail all the way over after installing.

All good ideas and washers and bolts are next if the black jobbers and pull ties fail.

Thanks again.

Yeah, I'm having a hard time understanding this. How are lynch pins coming undone? Even the cheapest ones I've seen can't open on their own.

Black s.o.b's ... they will pop your finger as hard as a 16 oz hammer and you can even loose your fingernail .... but they do the job and seem to last forever.

The Cadmium or zinc plated lynch pins (these are the (somewhat) gold colored ones) spring clips will loosen after some use. I've lost some when running my RFM (which I would think is a fairly low stress operation).

I think it is the India made ***** that just fails, I can't see why it would come off either and yes the flat was going to the implement side otherwise the ring would get smacked to ***** in no time, go figure. I feel it is must be inferior metals from off shore stuff no doubt. I have used lag bolts that use to be bullet proof but now bend like taffy hey but they are less expensive, lol.

I am thinking the lock pins that hold the lift link pins to my lower 3pt arms have a ring that you have to turn to release, like a split ring. I'll check my tractor and report back.

I only lose my pins when they walk off when I'm hooking up and lay them down! :laughing: :laughing: And I know this don't help you out but I think you are putting some stress on them and shearing them for some reason ????

 

[Deere Dude]

So you think that they are not breaking but coming unlocked?

Yes, I think they are being snagged, become unlocked and then fall out. Possibly, the ring can get ripped off somehow and then fall out.

I have had a few become unlatched from going through brush or digging them in the dirt and fall out, but caught it before I wrecked anything, but if I lose one with a 1200# weight box and then start dragging that through the woods with the toplink and one lift arm, that could be one for the video. :laughing:

If a branch will unlatch a light duty one, it may even unlatch a heavy duty one, it's just harder to do and may take a bigger branch.

I have never seen one break off, but I probably am not as hard on them as others.

Ya. Dam garbage. I wish the manufactures from tires to paint would stop making excuses and make stuff so it will last. A snow blower should have a cleaves style link pin setup. No. Instead they use one post and save 5 bucks. I for one am getting sick of buying crap.

Pins do have a split ring, hole in each end of ther pin, you thread the split ring thru the end hole to keep the pin in. JD part number AL114597

If you look at the image in the first post you will see not all lynch pins are created equal, lol, I like the idea of threading it through a hole but this was not an option with the pins I have been able to obtain.

HOw to loose linch pins blowing snow! I believe how it happens is..... We all hit things (curbs etc...). Because to many of the blowers are attached to a 3 pt hitch arms with a pin that is not a clevis style. The pin sticks out from one side mount of the blower, as apposed to a clevis mount, bends with a hit and abrupt stop. After the pins bend every force there after forces the arms off center thus putting pressure on the linch pin. Metal fatigue acts on the linch and eventually breaks.

Get the high powered black ones. But look out for them. They will bite you both opening and closing them.

Did a couple of days of Bush Hogging with no problems using the Black Lynch Pins, thanks!

I had a devil of a time yesterday when one of the pins came off one of my lower arms that goes on under the tractor. I finally got it all put back together and the mower hooked back up and put on the pins that have the wire come back and over the pin but I am confident a piece of brush will hook onto that and pull them out. Since the lower control arms under the tractor aren't ever taken off, would there be any problem with just putting a good bolt thru those with a lock nut? I have a New Holland TT45A. Thanks

I have a Quick Attach FEL Bucket on my Kubota B3300SU. The bucket attaches to the lift arms via four easily pulled pins, which are secured in place by lynch pins.

I had one lynch pin pulled out in thick brush, then the one pin backed out half way. This bent bucket frame which was $1450 repair, of which $1200 was fortunately covered by Kubota insurance.

This was after a year of ownership. The Kubota mechanic asked me how often I removed the bucket. I had to admit I had never taken the bucket off. He replaced four lynch pins with two 6mm X 35mm plus two 6mm X 45mm Allen head screws with nylock nuts. No problem since.

In the ensuing eighteen months I still have never removed the bucket.

That's the way mine are now (Kioti DK45), after a very scary experience with a rotary mower riding up a rear tire on a tight turn...damages thankfully covered under warranty.

I moved to the black lynch pins as suggested and have not had a problem with the mower since then

Just don't let the ring snap on your fingers...it hurts!
