Here is a vintage gem, filmed prior to 1950, showing how they mowed and made hay with a scythe in Mittelberg, Austria. It was posted on YouTube by feworieser. (If the music is too overwhelming you can click the volume button and mute it, and watch it as the silent film it was probably made to be.)
It shows what the traditional mowing with an Austrian scythe was like, before mowing with a side-shift. It also shows peening with a tall anvil, honing (Austrian style), and some very impressive technique with spreading the cut vegetation with a hayfork at 2:12. It also shows how they brought the hay to the barn with a garden cart, and bundling the hay with rope for carrying on the back from areas to steep for a cart. Most interestingly to me, at 3:34 and at 5:00, it shows how the traditional Austrian hay drying racks are used.
