That's well beyond my ability to make. I'm a master of MacGyvering simple new things together from my existing tools. Looks like something that every machine shop could use.
I had an epiphany last night, concerning my cordless hedge cutter. I'm going to attach it to the wheelbarrow or to a free baby stroller, in a manner that allows the cutter bar to stick out to the side at about 3 inches off the ground. It will be a small sickle bar mower for maintaining roadsides and for small scale
hay production. . I've already cut several thousand square feet and it works great, but I was bent over like a dummy.
