Old Ford Loader

[JW IN VA]

I keep seeing pictures on a tractor web page with a model of loader Ford used to sell with only one "boom arm". Does anyone know what the purpose was for them?
It looks like there would have been too much stress on the tractor. I seem to remember pictures of them being heavily counterweighted

Ford "one arm loaders" mounted to many an N, 600 and 800 series ford. They were from a time when the other option was a pitch fork and wheel barrow. They were no more stressful on the tractor than any other loader. Their purpose was like any other loader load and lift things.

Farmall had them too.

That's the first one I ever seen.
My grandpa wouldn't spend money on that he'd get a wheel borrow
