Looking for that special mulching tooth

[gvbrush]

Greetings! I'm a new member to the forum, but have been mulching since 2007. I recently purchased a used Fecon 9025 head and it had some teeth on it that I'd really like to identify. There were several missing so we can't use them, but would love to buy more if we can id them.
I think I can attach pics showing the massive tooth that I'm looking for, next to one of our standard "stone" teeth. Does anybody know anything about these monsters?

I coulda told you a few years ago who put those on our unit, but the guy who maintained the machine retired not long ago and I don't know how to contact him. I know they're out there, though!

Thank you for the reply. They just look like they could protect the tooth holders from our Missouri rock.

We had a lot of trouble with the head going out of balance so tougher teeth were an attempt at fixing that. It worked to a degree.
