I must say I was somewhat skeptical before purchasing this product but the price was too good compared to alternative grading options. Assembly was fairly easy and it does come with trailer pins. The item is pretty heavy and feels solid. The Chinese welds aren’t the prettiest but don’t seem like they will fail. Two cinder blocks fit perfectly in the center for some added weight. I have about 1000 feet of gravel driveway and 4-5 passes did a pretty good job. I towed this behind my zero turn with no issues. Probably not an option for commercial use, but for the homeowner to use 1-2 times a year this is a great affordable option.
