Best # of teeth on a tooth bar?

[Henro]

Was reading another thread about tooth bars.

I have a heavy duty one I would not part with, which has two flat bars welded together that slip over the bucket lip, with teeth welded on them.

But some compact tractor tooth bars seem to have a lot more teeth for a similar length, but perhaps not built as sturdy.

Guess this has worked well for me, but wondering now if more teeth are better?

It's a trade off, less teeth means more force on each tooth, too many teeth to the other extreme is the same as a solid edge on the bucket lip. Geometry of the teeth also make a difference as to the force applied to what you are trying to cut into. Beveled edges cut better than blunt. Different ground requires different cutting edges. Hence the different types of teeth and cutting edges.

I was looking for a answer that related to the practical side, rather than theory, but I guess the point is that it really depends on what you expect to (or might) do with the toothbar.

The one I have is quite heavy duty and basically indestructible on the B2910. Makes the bottom lip bullet proof as well. But that has nothing to do with the number of teeth.

Thinking about it now, I guess this was pretty much a pointless question.

I think in the back of my mind I was thinking that the toothbars with a large number of teeth seem to be less robust.

I will go back to my room now...

I made a tooth bar for a B7500 about 18 years ago similar to the description you gave. I think the bucket was only 4' wide, and with the number of teeth on it I'm guessing they're around 8" apart. It did work well the few times I used it for digging, but got in the way for everything else. Quick on and off, so no problem. It was my one and only tooth bar. Just haven't needed one in recent years.

On the other hand, the brush forks made for the L3200 that we sold early this year are dearly missed. Started fab on a QA set yesterday afternoon.
