This is an application where I find the old tech does a better job: push mowers.

I recently replaced my mower with an old push mower [1], someone local restores them and sells them for a reasonable price (much less than anything new or even a petrol or electric second hand mower.

It works so well I wouldn't go back unless I had more than about 200 sqm to mow. Modern push mowers are junk and put me off in the past, but the older ones are much heavier and better built. They cut grass cleaner than a rotary mower which is supposedly better for the grass too.
