SSQ Bucket falls off

Yeah, I don't get the wedges. They don't draw the plate in. What do they do? Maybe just pierce through dirt/frozen dirt and ice. But they don't tighten up in any way.

They pin the plate to the QA.

Does this drawing help?

Thanks. I meant the slant serves no purpose of acting like a wedge. Only, maybe to pierce an obstruction in the opening. Some Ag attachment systems do use wedges for a secure attachment.

I would be ordering up some stiffer springs for one thing.

Great news!
You aren’t the first person to have this problem. Back in about 2004 I had an L4330 with an LA 853 loader and the ssqa bucket would fall off. I posted my problem here back then luckily others had the same issue and gave me their fix for the LA 853;
Stack several large flat washers in the locking mechanism so the spring gets totally compressed. It fixed mine and the bucket never came off again.
Back then many others did the exact same thing.
I sold the tractor years ago for a bigger M95 or I would go take a picture of the washer set up.

Take a second to review his top pic. It clearly shows how they work. If you still don't get it then you'll just hafta take our word for it.

Presumably the ssqa and bucket were working fine until recently? And now the bucket falls off 7 times in a day. Ought to be fairly straightforward to figure out what changed.
Greased pins and no stop blocks. Previously the springs and friction were sufficient to prevent the pins from rising. Stop blocks make it impossible for the pins to rise enuf to get out of the bucket slots.

I agree. For high HP, high capacity systems the European method used by JD on their larger tractors is much preferred. The SSQA system definitely has limitations. Non of which have been approached by the OP.
Popularity of the SSQA ensures ready availability of a wide range of implements in that style.

What Tractor Mike said, I always raise the implement and look to be sure the pins are engaged. IMO, greasing aids in allowing the springs to keep the wedges self-tight. Up to a point, the more spring pressure the better, esp if they don't bind as they cam over. I cannot reach across from one side to tighten the opposite-side locking lever. If I could, I'd tighten or replace the springs, hoping not to rely on the blocks alone.

Wear on the OP's tabs looks to be made worse by the bucket falling off so many times. I agree that shimming the lower plate to tighten the fit might help, say test-fitting spacer metal into the gap with the bucket attached to determine a fairly snug fit. Then, I'd want to be sure the downward limit of pin travel allows contact hopefully on the upper half of the pins' tapers. It was asked about.

btw, can you say "stacking tolerances"?

Gene has the answer. Apply more pressure to the locking pins so they can't work up and out of the slots in the implement. Greasing the pins may be making the problem worse too. Grease can help the pins slip in the slots easier but it can also help them slip out of the slots easier.
