Interesting dozer "blade" video
 

I happened across this video today and I thought somebody else might like to see it. I've never seen one of these in real life but I think it's a neat idea and would make a cool project for someone. I wasn't sure if this was the best location to post this so feel free to move this thread. Also, I haven't seen this posted before but if it was I apologize in advance for the repeat. Anyway, here's the link to the video:

I seen this on Discovery a few yrs ago.. I recall them saying this attatchment turned 3 passes into one. I believe this is used in pipelining quite often for removing topsoil to the far side... I doubt not so much for filling trench as most areas have alot of rock within the subsoil.
