i saw this guy, he had an attachment on the front of his walker. he was doing spring cleanups, and this attachment was like, "tines" i guess you could call them. they were scraping up the little twigs and debris from the grass, and the mower was sucking it up. my question is, what is this attachment called, and do they make them for walk behinds? my dealer said no, but, he also said they don't make striping rollers for walkbehinds . anyone know?
