we bought one about 10 years ago and it has held up remarkably well. We primarely use it in the mountain where it hits numerous rocks. It's heavy enough to cut up most any soil as long as it's not just bone dry. I wish I knew the manf. but I don't. All I know is it is red, has 6 discs and rotates over for discing and then rotates back over onto 2 wheels for travel. Probably weighs at least 300 pounds. It is not very wide, probably 4 feet but you can go pretty fast and cover a lot of ground. Speed often helps when discing new areas or hard soil because as it bounces up and down a little it digs into the soil better.
