>Richmond, Indiana was an improbable sourcing location for local
Yes...and no...
The reasons why it makes sense are convoluted tho. The iron wan't in indiana, the iron was in the great lakes states, iron ore is half rocks, so you build steel mills where the iron is, but for processing the iron into other things, the transportation is more important, so you build the rolling mills in indiana where the railroad tarifs are equal going both east and west.
And where you have a rolling mill, you have cheap sheet metal, so you build your stamping mills there also. And lawnmowers are 90% stamped steel parts....
There were lawnmower companies all over the place, a few of them failed, but oddly, I found most of them got bought by other lawnmower companies, untill there were just a couple left, some of which remain, tho they make gas lawnmowers these days....
(I wonder if the Amish do in fact have hand lawnmowers, a mown lawn is kind of a vanity thing, and a goat does the same thing and you can eat it afterwards...the Amish are very practical...)
