wood cooking ranges, hand crank cream seporators, cream cans, horse drawn farm equipment(one row of anything) ever do 10 acres of corn useing a one row lister? let alone 40 or 80 acres?, beavertail slide stackers, hand milking 10 milk cows, lighting by lantern, useing a privey, hay mows, root cellars, ice houses and cutting ice, corn cribs, hay knives, hand shucking ear corn, corn knives, walk behind plows, hauling water, boiling water, bucking, hauling and stacking wood all were labor intensive, they came out with labor saving devices to free you up to go do stuff.
I love my front load maytag washer, push 3 buttons and a scoop of detergent and its doing hours of work for you, same with indoor plumbing,
I'd keep something like a scythe as a last resort but even then I'd most likely use a gas powerd commercial grass cut/ brush cutter instead of the scythe.
labor was hard thats why families were huge and everyone pitched in and helped pick corn or stack hay, it was hard and some people just couldent dedicate ther lives to spending weeks cutting just hay with horses to tend, crops, basic house chores and farm chores, you'd be run ragged and you would have to get up at the crack of dawn just to get anything accomplished. work till dusk and felt you were behind the curve the whole way.
