Couldn't find a box blade used locally so I ordered one on line at HD. It's the Brinley 38" and it arrived today. The packaging was beat up pretty bad but all the parts were there and it went together fine in less than an hour. The centre hole in the hitch was partially deformed and i had to file out the excess metal. I haven't had time to put it on the tractor and try it yet. I stopped at 2 places on the way home and couldn't find a 5/8" pin long enough. When I got home I checked my parts and I already had one that fits perfectly. Heres a few pics. That weight bracket is a lame idea! It's too low! I'm going to change that to something I can hang steel weights from.
For the price 209$ it isn't too bad. I plan on trying it out soon at the church parking lot to pull gravel back into the lot from where the snow plow has piled it over the winter.
I have this exact same one for my 317. I have used it for everything from gravel to snow removal. I like it quite a bit and really appreciate the removable sides. I was suprised and how solid it was for the price.
