Great build, still looks like lots of work to search and destroy. Does that single plow blade need much tractor horsepower to pull them out of the ground?
The good thing it makes great smoking wood. But what trouble having a patch of that must be.
When I bought my home in 1984, the previous owner put in a small shrub of some unknown to me plant. I let it grow, turns out it was some sort of Bamboo plant that sent runners everywhere. I couldn't find a weed killer. But I kept mowing it till it disappeared.
The other plant is Horseradish, I've heard horror stories of using a roto-tiller, which was the wrong way of removing it.
