I have a 45" Farm King. They call it a 48" when they sell it to you. I've only had it a year and use it in sandy soil so I can only say say that for the time I've had it it's been fantastic. Farm King is part of the Buhler/Allied/Versatile group and they make everything from blades to Loaders to Monster 4x4 tractors. They are all well known in the AG industry around here and have a pretty solid name. Check out their website.
