A couple of weeks ago I decided to put to use a 48'X12"X1/4" piece of curved steel plate that had been laying around the shop for years. It was originally intended to be used as a mid mount grader but was too tall and would have been a real chore to rip lengthwise. I opted instead to make it into a rear mount grooming blade with 1-1/2" scarifiers. Used it for the first time today and it worked great, just wish I'd gotten around to building it years ago.
Here is the finished product attached to the little 7hp Wheel Horse 704 after a few passes on the the driveway. When snow season (if we get any) is over it will go on the 416-8 for spring cleanup.
