Re: Please help! does anyone know what "rake" "tedder" this is and/or value ??
I've seen a few like this around, and I've heard folks call them David Brown or David Bradley rakes. A quick google search shows some that look kind of what like what you've got, but most of them have rubber tires, so I'm assuming this unit might preceed those. It looks like it was intended to be horse-drawn, given the size of it and seat, but sometimes folks will add stuff like that. Beyond that, I really don't have any idea.
As far as what's it worth? What does it weigh? Unless you find a collector, it's probably worth about $110/ton (at least in my area right now).
Good luck and take care.
