True! I mow my lawn with a push mower for the exercise. Neighbours think I’m nuts. I have toyed with getting a scythe but I have pets and the unthinkable could happen.
I used to use a scythe. It got a lot of thumbs up and such from passers-by. It's a pretty fun way to cut the grass; if you sharpen the blade nicely it's surprisingly effective. I used to use it in combo with a push mower, they're good on that super long grass that your push mower can't get through.
Nowadays I've succumbed to laziness and convention and use an electric trimmer and mower, but the scythe still comes out once in a while for kicks.
Something about the relaxed and repetitive motion, doing things a little differently and without a noisy machine, and of course the imagery of Death personified, reaping Souls.
It'd be pretty hard to hit a pet with a scythe used correctly, as you have full control of the blade at all times and it's pretty easy to stop/divert if necessary. I'd rank it about as dangerous as a push mower, which could catch a tail I guess.
My dad got one years ago from https://scythesupply.com and it works great, especially with the longer/taller weeds. Looks like they only have left-handed ones in stock "right" now.
Push mowers are actually best for the grass because of the scissor-like action, especially if you cut it low. I use them in combination with a scythe to cut long grass (I let it grow in the colder months).
That's the inspiration behind the shovelglove exercise routine - use a big hammer with a weighty end for exercise, keep it mildly interesting by pretending to be doing labour work with it (shovelling, among other things).
Mopping a floor by standing on a rag is great for the core.
