    What a way to make a lot of money, I am sure with the amount of compact tractors being bought today by do it yourselfers and people with large lots and not much time to take care of them someone could make a lot of money. I have an 8 hp giant vac push blower, there new design, it works extremly well. I would gladly by the exact same model for a 3 ph with no motor, even pay the same price. This can't be that hard with all the computer drafting out there.

    Why not investigate the possibility of pulling the motor, adding a splined sleave (set with woodruff key/bolt?) first, PTO shaft, and 3pt hookup (recommend tempory setup until you see if works to specifications) and give it a try?
    If done with care, you should not damage the unit, at least until you decide if it will work or not.

    If you take a blower that is designed to operate at 3600 RPM and operate it at 540 RPM it will not work very well at all. The result would be very little flow and very little static pressure. It would be like the engine mounted blower running at idle. A gearbox or belts and pulleys to increase the PTO speed would be necessary to get good performance.

    Larry, I will post pictures as soon as I am allowed to.

    I guess you could call a radial blade impeller a centrifical fan. If you look inside any leaf blower they all use the radial blade design. The reason I mentioned the different types is because of the idea of using the blower from the welding fume apparatus. Often exhaust vent devices use the other types of blowers because they are quieter. These other types will not work well for a leaf blower.

    If you do make a PTO blower I would suggest starting with a blower much larger than the type found on a 5 to 8 HP push blower. Since a PTO usually has much more power available than 5 or 8 HP, why not use it on a larger blower. The larger blower moves much more air and because of this, many more leaves quickly. What used to take 2 to 3 hours with my 5 HP push blower takes about 15 min. with the PTO blower. It is also a lot more fun. I have to be carefull, since two times now, I have blown my wife's flowers near the mailbox right out of the ground, root ball and all. The blower puts out so much air that I typically have the adjustable discharge nozzle I made for it half closed. I also usually run it at only 2000 tractor RPM (PTO speed is at 2600 tractor RPM).

    I have been clearing the neighbors yards for them since mine is done so quickly. The guy up the street has a 5HP blower that he mounted a trailer hitch on and tows it behind his garden tractor. After seeing my 3 pt blower he went out and priced them.
