In a June, 1912 issue of the Pierz Journal this ad for Jacob Neisius' store puzzled me. I know what a scythe is cuz dad had one, but the word snath is totally new to me. Still, it would have been in the vernacular of our farmer-ancestors, so....I googled it ☺.
Turns out they're still sold--'snath' refers to the handle of the scythe, I think, and whether or not it's the right length for you is important.
I assume that most farmers had horse-drawn hay mowers but that a scythe was needed on smaller or less accessible areas on the farm...or if you couldn't afford a mower. More pics and explanations HERE from the Oliver Kelley farm in Elk River, Mn....where the pic below is from.
For sure, mowing a field with a scythe would be tedious and slow, but just watch the rhythm this man sets up, out there in the sunshine, with birdsong and the breeze. He has time for contemplation, I think.
