$25 each plus shipping if you need one. The 15 tooth is a +1 on the tooth count over factory

What is the purpose of the 15 tooth? Speed?

[ol'George]

Yes it increases auger the speed, I can't remember how many rpm's, I'd have to do the math again.
Do remember you should have a higher Hp engine to utilize it effectively.
I'd say @ least 14+ hp.

ol'George is correct, it gives a faster auger speed.
