Came across a "Verti-cut" (made by West Point Products) at a consignment shop. Looks old. 3 1/2 hp B&S engine on it, but could not find numbers to get the date. Rugged machine, runs fine. Much like a dethatcher, but has spinning blades. They wanted only $75 for it, so I bought it. Not sure if it will be of any use to me. These things still used? What for?
