I was just doing a Google search for info on the Victa18 edger attachment, and saw this post.
I've joined the group now, but the link to the picture you put up doesn't show anymore.
Are you able to re-post it?
Someone else put a link to some patent info, and that doesn't show now either.
I'm really stumped as to how the edger was supposed to be driven, and what it looked like!
Any info/history you have would be greatly appreciated.
Thanks!
