I tried this thing out tonight and I like it, hooked it up to my MF10 and it has no problems pulling it, blade is wider than the tractor by 3" or 4"each side, found that it works best going slow.
I didn't like the bracket for the block weight they had on it so I took it off, the blade seems a bit light on hard packed gravel but on loose grave it's good the way it is.
I think for me to use this on my driveway after a rain it would be great.
Doug, sorry I missed it before, but that is a nice looking blade.

As for weight, I think I am going to add a few pounds by putting a heavy wear bar on mine. I have a piece of 1/2" plate just about 2" wide that should do it.
BTW, I moved this out where more people hopefully see it.
