The driveway is 900ft long, 10ft wide. Had it graveled couple years ago. Driving on it, snowplowing during the winter, etc spreads it out. I made a heavy duty float, it does a good job. But some of the gravel ends up in the grass. So I get to shovel that back onto the driveway, that gets old fast. The 560 IH, W450, SW6 don't have 3pt hitches. Not sure if they would even fit with the fenders they have. My Dad got a H couple years ago with a Artsway 6ft belly mower. I seen a 6ft blade for sale locally. Brought it & have been mounting it to the back of the H. It wont be used that much, so the pulley that drives the mower has to come off. Its not a true 3pt hitch, as have unbolt pieces. Don't have too much $ into, I'm happy with the way it turned out. Image there is a few things wrong with my setup. But its just going to spread a bit of gravel once & awhile
