    I have never run a pto shaft so I know very little other than what I have read.

    Looking at your shaft it looks like the angles are wrong. I believe that shaft should be hooked up as straight as you can get it. It looks cock-eyed to me. And it looks like the connecting point at the blower is very low.

    Take this with a grain of salt...I am no expert. Let others chime in to comment on your pictures.

    Hope you get some help.

    I also don't understand what the second shaft connection is for. If you disconnect the PTO shaft and turn the auger by hand, do both of those shafts turn? Is it possible there's a gear reduction that allows connecting to different speed PTOs depending on which shaft you connect to?

    I don't suppose you can call the guy you bought it from and see if he has any ideas...
    You are correct, the fins are bent. If you are looking right at the impeller, they would be bent to make kind of an "L" shape to the right. To kind of scoop the snow up the shute.

    It appears that the other shaft makes the impeller turn the other direction. I guess you could hook this up to a PTO that spins in either direction.

    So, is it just a RPM thing?? How fast should this thing spin?? If is is not spinning fast enough how could we speed it up?

    That impeller has to turn counteclockwise in picture 2 or clockwise looking from the tractor. So which way does it turn???

    Is that gear box a 1:1 or is it an increaser???

    At 540 RPM, I would expect it to look more like a blur.

    Rotation would be counter clockwise.

    Several recent snowblower threads here on TBN have mentioned a marked improvement in snow blowing performance when the impeller and chute are clean and slick. Trying spraying the impeller, impeller housing, and chute with silicone spray and try it again. Also, you are running the tractor at full PTO speed right? If you see improvement you may need to repaint and slick up the snow path. One of the other TBN'ers posted a link to this paint that looks to be a good choice for this use.

    The two different input stub shafts seems odd. I don't know if its a picture illusion, but the shaft that your hooked up to seems to put the drive shaft at an angle. The other input shaft looks to be more in line with the top link which would seem to make the driveshaft connection straighter. If so, I would probably connect to that one.

    Those are both correct. Looking at it, it turns counter clockwise. From the tractor, it would be clockwise. I don't know anything about the gear box. I do know that the PTO, looks like it is spinning a heck of a lot faster than the impeller.

    Thanks for the link, I will look into this. As far as PTO speed, my manual says 2200 rpm for 540 at the rear PTO. This is also marked right on the Tach, as well as a mark for the mid PTO. Even at 2650 RPM which is the mark for the mid pto, I can still see the individual fins on the impeller. Not what I would call a blurr.

    Just an observation from looking at the pictures ...... isn't the angle of the pto driveshaft extreme ?

    The left side view which shows the chute motor looks a little radical.

    One of the other snowblower threads said that a 540 RPM snowblower impeller should turn at 540 RPM. Rotate your driveshaft 1 turn and check if the impeller rotates 1 turn.

    Hooking up to other input shaft makes impeller turn the opposite way? I would say THAT is a big difference. The impeller is turning the correct way (CCW looking into blower) hooked up the way you have it.

In the picture looking in the blower, the impeller spins counter-clockwise which seems to make sense because there are curved edges that would throw the now up and out of the shute. Let me know what you guys think. Also, what is the other shaft on the back of the blower for? It was obvious that the one we are hooked up to because it was the only one with any signs of use. We did hook up to that one but it didn't seem to make a differance.

    Thanks all!
    The other shaft is probably there just in case the one you are using is turning it backwards. It looks like there is a gear set under the cover and the shaft that you are connected to is probably supposed to be used when the blower is front mounted to get it the turn the correct way. As it is now the impeller is probably turning the oposite direction of your pto shaft.
