I saw a video of someone cutting their lawn so I think it may be possible, but tedious, so from seeing that vid I figured weed whacking here and there might be doable (this was my thought process anyway, they do look like a challenge and easier to use on a meadow like you say)
manual lawnmowers seem like a cool idea, or allowing grass to grow in to meadows (no mowing) or letting animals graze, where that kind of thing can be done
