For that small pin to move up far enough and the big pin to have the weight off it and rotate,so small pin doesn't go back in slot and then have the big pin work it way out that's a lot. Freak deal. My brother put mine in and didn't drop the small ones in there hole,helping me but I noticed it when he done it and corrected it,first time he been around taking the loader off,he just leaves his on his mahindra. Its so easy I take mine off unless just really need it.

But if you think about it, they both don't have to fully disengage at the same time. The small one could have jumped out and the large pin turned a bit so the small pin didn't go back in the hole. Then the big pin can take it's time coming out. The machine gets a bit more shock and vibration when plowing snow up here in the north. I agree it's a freak deal but it happened and Kubota doesn't seem to care.

Don't take me the wrong way,not saying it didn't happen just saying,the chances are minimum of that happening but that's why we have insurance. I have never in my life broke a window out and done it twice last year...

Threads like this is why I like this website. 95% of posts are in support of the OP and trying to find a fix. AND, brainstorming with multiple heads always yields the most efficient fix to the problem.

My spring idea was to use a compression coil spring about 2" long that would slip over the small pin. Add a washer. Drill a hole for a cotter pin that to install would compress the pin and put tension on the coil spring, thus holding the small pin in the lowered position. I still like that idea because it has an extremely long life.

With that said, the ideas about O-rings sparked my imagination. Took me about 60 seconds to get an Oring out of the assorted box and install it on the pin. Here's photos. First is with the O-ring on top for better viewing of what it accomplishes. Second photo is with O-ring in useable position. To lift the pin you must roll the O-ring. No vibration or shaking of the loader is gonna do that.

Very nice solution. It looks like you won't see my issue in the future. My mechanic came to look at the tractor today. We're going to detach the loader assembly, remove the left main frame plate, heat and bend it back in place and reassemble. Thanks for the idea!

If you don't have an assortment of O-rings to dig thru, pull the large pin and take it to an Auto Parts store like O'Reilly's and they can hook you up with a pair that will fit. You want it to roll onto the pin very snugly.

I still like the spring idea better for longevity. After a few years the O-rings will probably give out, especially if your tractor is parked outside or in an unheated shop.

Post some pictures of the repair to the loader frame. I'm very interested in a writeup about how he does that!!!

I made it to the store and bought a couple springs yesterday. Rigged up a solution. I started another thread so I wouldn't distract from this one. I still want to see the repair to this loader.

Here's a link to my spring fix.

I have a fairly new (65 hours) Kubota M6040 with a LA1153 loader that I bought new. While moving some snow yesterday, one of the 2 main pins that holds the loader assembly in place, fell out. I was pushing snow into a bank and the failure caused the loader to swing to the left thereby bending the main frame on the left side. My dealer, Chappell tractor of Milford, NH said it will not be covered on warranty because there is no broken part that caused the problem. The poor design of the pin that does not keep the pin from falling out is not a "broken part" so tough luck for me. The service manager said that both Kubota and New Holland have the same pin design with a sliding pin the goes through a hole on the frame. It seems to me that a jarring of the tractor during normal plowing operation could allow the pin to dislodge and fall out. He said it has never happened before. Personally, I think the sliding pin should have a hole drilled in it and a spring pin through the hole to prevent the sliding pin from disengaging. I plan to do that fail safe myself once the tractor is repaired. In fact, the LA1153 owners manual states under "Reinstalling the Loader Important: 6. Stop the engine. Reinstall the mounting pins and secure them with the spring pins." So someone thinks there were or should be spring pins on the assembly like I do. Anyone else have a similar problem? Thank you, Jack

Here are some pictures of the failure- the side where the pin fell out and the bent main frame on the other side.

Wow that really is a shame. Are you going to take that bracket off and have it pressed back into correct orientation?
