Shaft broke awhile ago on the impeller in the ford blower. So I figured it  was quite a chore to get the shaft out of the 35 year old piece. So figured it would not cost much more to make a new impeller. So why not change it a bit, add one paddle, change paddle design and make them closer to the drum. Cost was under 100.00 for metal, bending, welding, paint and clear coat. So, don't know yet if it will be any better.  Hope to put it in tomorrow and try it.  Noel

 

 

First two pictures are the original impeller, the next six are the new impeller.

Is the extra paddle why you notched these?

I weighed all the pieces before. Spun it on the shaft, did not seem out of balance. Can get it checked at a local shop for balance if needed.

I made the paddles the same way they are in my walk behind snow blower and most farm tractor blowers are made this way. Noel.

Never had a blower, so I was just wondering. Haven't seen the insides of many!

Another thing is, I read some where, that it took less hp to run a impeller with more paddles. So I went from 4 to 5. Noel.

I understand Kenny. I just think everybody knows about blowers. Hope I said that right, hard to get a meaning across these computer things sometimes. Noel

There's not many of them around down here to look at! Most of the time, our snow isn't worth even pushing as it will be melted within a few days!

The snow that comes in to the center of the blower may need to have full paddles to start the centrifugal move to the outer edge to be thrown up the chute. check it out though before you make changes, it may spit the snow forward. looks like you did a nice fab job. gene

Awesome job Joel!! That should work awesome. That paddle design is common, and will work just fine, it will chew up hard chunks before slinging them out the chute.
