The herbicide will coat everything under the rotary cutter (brush hog). So wouldn't it kill it all, rather than be specific to the stump of the brush he wanted to kill?
Also, seems it would take a lot more spray, to get the right dose on the stump, whilst coating everything else in the area under the cutter.
Just seems a bit inefficient to me. Maybe others will think more of the idea, or know that it works good.
I've heard of similar ideas on hand-held brush cutters with blades for cutting....run a herbicide onto the blade. But also heard that it flings the herbicide all over the place...and very little on the top of the stump which remains under the blade after cutting.
Bear..nice place but you can make the pics bigger and easier to see.
