I picked up this blade this summer. It was new-never used-but must have been sitting out for years. I purchased it from an old time dealer. He has to be approx. 80, and very sharp in the head. Has acres of "stuff". I located it by phone and had to chuckle at his reply, when I asked ""who made it?". He said in a more than slightly aggrevated voice. "I don't know, what does it matter? It is rugged and you won"t be able to damage it with your 65 hp tractor." He doesn't like to waste time on trivial things. /forums/images/graemlins/grin.gif
There is no brand name on it. Sticker on front is from a epuipment reseller that he must have got it from.
Well, he was right. It is very rugged. The turning plates are 3/4" thick. the blade is 1/2", and reinforced quite a lot on the back side.
