There was one of these powered weed removing machines for sale locally for about $100,000. No idea what they actually got in the sale or what they cost new. They come with an outboard powered sickle mower and also front attachments either for digging/lifting rooted leaves or a mesh for gathering and pushing floating weeds. Maneuverable, powerful. I don't know if there are several varieties of these machines and I'm not intending to advertise one brand as I have not personally run or seen the results but just sharing what another inventor came up with. Happy to have the links deleted if they break any rules.
