I am wanting to build a bulldozer and was wanting to know if annyone else has? How would it be done?

The easiest way would be to just use a lower tank hull for your drive and then use the turret or gun elevation for raising or lowering the blade.
You could also buy a Sherman kit and scratch build a dozer blade used durring WWII.
You will need extra weight in the vehicle if you plan to push sand.
