After I posted the question I went looking for videos. The videos I did watch it did look like the suspension was over used so I’ll probable resort to using a shovel and trailer to haul and move sand and dirt around.
I have used one of these ATV buckets once before. It was mounted on a Honda Foreman 450. While it did work, it didn't work very well. An ATV just doesn't have enough weight behind it to effectively use it in anything solid. In sand and crush stone it worked ok, but not great. Additionally, the weight on the front of the ATV was quite substantial with a load in the bucket. A full load of crushed stone or gravel felt like it was going to break something.
To put it simply, ATV's are just not meant for this purpose, and this is the reason why it doesn't really work that well and this is also why they never really caught on like the snow plow did.
And to add even more to this. If you only have 1 or 2 jobs to do, for the cost of buying this bucket setup you could rent a Kubota tractor....and get the job done faster, easier and safer. Using the proper equipment for the job.
