Interesting, went to the their website and watched the videos.
Don't know how well it would do around here. We either have lots of rocks, or fairly good soil with a few huge rocks here and there. But always seem to run into at least one huge mother in each trench in the good soil.
Never been able to figure out why these huge rocks are here. The good soil hardly has any small rocks at all and then these random huge rocks sitting there all by themselves.
thats pretty cool, ive actualy been thinking of fabing a pick type of attachment for my hoe thats 4 feet tall and 4" wide for trenching water lines (meter to house) but i've never done it for lack of a good way to backfill a 4" wide trench with native...
it looks like backfill and cleanup might be tough.
