Building a burn blower

One of my winter projects is going to be building a overgrown trench burner. and I need a blower, I have a spare 4-71 Detroit powerplant with a 4:1 speed reducer P.T.O. box on it, my origional plan was to take a large ventilation blower out of a factory that I found and marry it to the powerplant, however the blower I had hoped for was un-obtainable, it had a 80hp electric motor on it :notworthy I will take the two units and put them on a steerable axle from underneath an old trencher and run it off a hyd pump on the motor, also build some deflectors to help direct airflow to brush pile etc.......but with no blower it makes it a little difficult :help: We do alot of heavy land clearing and I believe with something large enough could cut our burn time down drastically in turn saving money also, it may sound a little crazy but I have also thought about a old outdated jet engine but is proving to be a little hard to find....imagine that lol I would like some pictures of your burn setup and if anyone out there could come up with a blower I would greatly appreciate it Attached is a pic of the ductwork that came off the blower and I was really hoping for something about the same size Pj

I had used a cheap 120v leaf blower blowing into the bottom through a pipe Kinda helps, but it's annoying and after a while the dumpster fills up and the hole gets plugged.
