Hydro-tilling with a pressure washer

Ran across this guys youtube channel using a pressure washer for weed control or clearing an overgrown bed. The oscillating tip kind of makes it more controllable than just scouring with one of the given nozzles and seems to chop up the blades etc.

Tried it out today and it has some potential. Makes a mess of course, but pretty good for edging.

One interesting thing is that it takes a lot longer to cut through st aug stolons.
