So I was up at the Farmall museum in Avoca, IA today and they had a few displays of some old IH wrenches. Try to guess their application. Its not what you might think...

It is for disassembling and re-assembling steel detachable link chains. These are used as drive chains on various old machines, and as conveyor chains. The links are slotted, you slide the link into the appropriate size slot in the tool, pull the handle to bend the chain until the slot in one link lines up with the sides of the next link, then beat it with a hammer until the links slide apart, re-assembly is the reverse. If you don't have a tool you use vise-grips, channel-locks, hammer pry-bar, whatever, smash your hand, skin your knuckles, and take twice as long to fix it.

I did some searching, and chains are used in this particular application.
Most of those are plow wrenches. But I'll bet there are wrenches for just about any equipment IH made on that board.
My dad, 80 years old, gave me several of those type wrenches. Dad said he had kept them from when he worked on the farm in the 30's and early 40's. Said they used them on plows and anything else they found they would fit.

This type of chain was used on row crop planters and other seeders where a wheel would drive the seed meter and you would change spocket sizes to adjust the rate of seed drop. Then you would have to add or remove chain links to fit the spockets.
Image changing 8 to 12 row units (2 spockets and chain per unit) out in the field with a pair of pliers, "Cresent" wrench and a claw hammer using the planter as a work bench.

The middle "1893" wrench is cast iron. It would be function on low torque stuff ONLY. That is unless you wanted to break it. They aren't very strong. The International how ever is fully forged. These old wrenches are typically forged from carbon steel and don't have the strength of a modern "alloy" tool. They are so thick you can't really hurt them. They also bend substantially before breaking so you know when to stop pushing them.
Those "binders" are good trucks ! They'll really do some work for ya.
Im sure youre all probably right, but the museum guy told me they were mostly for one particular application. No one knows????
...or a turd hearse.
I have the disease called "International Harvester Collector". Here are the modern day IH tools (by Wright) that I have in my collection. IH sold these tools thru the 70's and early 80's.

I need to know what a "turd hearse" is!

But don't they fight with those sweet Bonney-made John Deere combos of yours?![]()

Agreed, but real gas guzzlers though! They also sound like a school bus when you are following them! Just about as fast too, but speed is not their strength is it!![]()
Milk pump?
Looking again and paying better attention this time I see that there are a ton of repeats in that collection. With the chain splitter that narrows it down to a hay bailer, combine or a turd hearse. No, I can't guess any closer than that.![]()
Very very close...

Manure spreader
The old pull type used a chain driven by the wheels to turn a pair shafts with paddles to throw the manure out the back.
