The ballast box is fit of purpose and built strong enough for the price point. The supplied 3 attaching pins are perfectly fine but I chose to drill out the through holes and fit round linch pins rather than the split type (personal choice). I also chose to reweld new lower attachment points to suit my 3 point quick hitch. Nothing wrong with the originals but they were too high up for my quick hitch. If you use the standard adjustable top link, you won't have a problem. Happy with the overall result and it makes the loader much more stable...
