Before spending that kind of money on a box blade unit of any brand, I would think more about what you intend to be using the box blade for. If you will be working dirt that has clay in it, or the dirt has moisture in it you will have problems with the dirt packing hard between the front and rear cutting edges because the rear moldboard is not hinged. When that dirt packs hard between the front and rear cutting edges your box blade unit just wants to float on top of the ground and will not be cutting good. The weight is good for the grading purpose and helps when docking down fresh mounds of new dirt, but when you have a lot of weight and no hinged back blade you can be spending a lot of time digging out the packed dirt between the cutting edges.
