I guess this is classified as "stuff". A few years ago I was at an Ag show in Moultrie GA. They had blades for lawn tractors that looked like hay bind blades. There was a round flat piece of steel that bolted to the shaft where the blade would normally go. It was like 9" diameter or so. To that was hooked 4 floating blades per round piece. (3 on my John Deere, 48" deck). Does anyone have a clue what I'm talking about? I've searched the net to no avail.
