PineRidge,
I found this in an article from a google search:
"I saw an advertisement in a Texas trade journal describing a new piece of equipment call the "Curb–Dresser." It has a disc wheel with a box to mount weights that could be attached to the three–point hitch of a tractor. It cost $500. I ordered one to use on that project. With the Curb–Dresser, we were able to edge that eight miles of turf in just three hours instead of five man days."
