I’m pretty sure they also sell single links. It just folds together. I think I have some hanging on a nail in the tractor shed. If you can’t find single links, PM me your address and I’ll send you one. I’ll check tomorrow to see if there are any out there.[/QUOTE]
Those are the same kind of chains, mostly came in two different sizes, that we had in our Dempster drills.
There is a little tool, called a “hand”, that you can use to take them apart and add or take a link or several off.
You can also punch the links apart with a screwdriver and hammer, but it takes longer.
I am not sure manure spreaders would work with those chains, they are not that stout, at least not the sizes we used.
Tractor Supply has different kinds of farm equipment chains, see what they have where you are.
Here is one of those:

OP, could you take a picture of the chain, see what you have there?
