HI, I have the Auger with 8" bit. I need to install some 14" sauna tubes for a saw shack I'm building for my mill. Does anyone know if I can run a 20" or even 24" auger bit on this thing? My tractor is a a 3902 HST. Want to make sure if I get a large auger bit that it will work. It will be on flat ground in a field, not expecting to go through much shale. Any advice would be great!

need to know the quality of the auger / gear box (make and model #'s) and your soil conditions before any semblance of accurate advice to be given.
Tractor itself is more than capable in medium soils with a good quality auger / gear box and a careful operator.

Hmm...just a guess here, but if you "peck at it" I think you would have a better shot at success.
One thing to concern yourself with might be the amount of increase in "radial speed" your going to get with an auger that size.
Just a thought.

How well does the 8" auger work in your soil?
A little quick math and ... With a 20" auger you can expect to need (20 - 8) ÷ 8 = 1.5 , or 150 % MORE power to the auger.
With a 24" auger you can expect to need (24 - 8) ÷ 8 = 2), or 200 % MORE power.
And those calcs don't consider spinning mass or the elevator flutes bringing up dirt. That's just cutting edge power needed. Correct me if I'm wrong.
Sounds like backhoe or mini excavator work to me. Or auger (3) close 8" holes and knock the center dirt bridges out by hand.

I'm not sure if that equates to 200% more power, or 200% more "required" power......Since I started drinking 30 minutes ago, I let the sober, smart people take over the "heavy lifting".
Carry on.
As you were, RWS.
But a 20" or 24" auger is massive. I don't think the OP will have enough HP, tractor, shear pins, or patience.

Yes sir, I tend to agree, it is pretty big.
I suggested a "Just maybe" scenario.
My name is RWS and I have successfully "pulled off" more than my fair share of "questionable things"...
I have also spent more than my fair share of time in the ICU....
OP's calll.....
I like you logic but isn't your math on area something like A =π r r
so area of 8" = 50.27 sq inches of surface area to bore
and area of 20" = 314.16
and area of 24" = 452.39
so your conclusion is dead on I think (more power needed) just much much more extreme??
Yes, exactly. I didn't factor in elevator lift friction or weight of material or mass of the auger. Just cutting edge basics.
He'll be over the top with not enuf power.
You are correct.
If we get serious with Pi, I prefer apple or cherry. With a dollop of vanilla bean ice cream. Just kidding around.. But you are correct.
