I favour a sort of cyborg-mower: it ambles around the grass by itself

the sewer system where its faeces (along with waste from human
sources) are converted to methane to be stored for useful purposes.

It ought to be possible to genetically engineer cattle in much the
same way - it would save the farmers a lot of work. One can
toilet-train dogs, so why not cattle?

Different brains.

The last thing we need is clever cows. They would learn that the electric
fence isn't always on.

Yeah, went to this last year.

They had what was allegedly the longest bullock train ever seen
this century, and its such an old fashioned operation you were
welcome to wander around where they were breaking up the
bullock teams and putting them onto the B double trucks.

They do that up an earthen ramp that the truck backs up to, with
quite literally just a very long piece of string up the side of the ramp
to stop the individual bullocks heading off the side of the ramp.

Being able to find their own way to the milking parlour twice a day is
quite clever enough.
