That NOS plow is $400. Plus another $100 for shipping. $500 is alot of money.The proper blade for a 1476 would be the one on which the angle is adjusted manually. $300 does seem like a lot. I found one in Indiana a couple of years ago for $25 on eBay. Of course, as luck would have it, I had a 6 hour round trip to pick it up.
There are some snowcasters around fairly often. You could get one and use the frame from it to mount a plow. Then you could get most any plow and figure out how to mount it on the frame. I just got rid of a large frame snowcaster a few weeks ago. Just an idea for you.I have been having trouble finding a good plow too. I have plenty for tubeframes, but nothing for my Large frames.
