Switched to a different cutterhead tooth profile on Monday...

Been running the same standard chisel teeth on our 12-inch cutterhead for two seasons now. Last week I swapped over to a set of those bullet-style teeth I saw at the Tampa equipment show. First two hours I was worried because the production rate actually dropped off. But once they broke in around hour four, the wear pattern was way more even and I didn't have to stop and replace a single one. Has anybody else had a long break-in period with a new tooth shape or was mine just a weird batch?

The same thing happened on my 10-inch machine last month. Those bullet teeth took a solid four hours before they started cutting right, but then they just kept going and going. I was ready to pull them off and go back to chisel teeth around hour two, but a guy I trust told me to wait it out. The wear got way more even after that break in period, and I ended up running them almost two full days without stopping to change a single tooth. Your batch sounds normal, it's just how these things work.

Did a buddy of mine swap to those bullet teeth on his rig last spring? He said the first four hours were brutal, thought he wasted his money. But by the end of the day he was praising them like they were the best thing ever.

Oh yeah, I've seen that pattern a bunch. From what I can tell it's not really a break-in period though, more like the operator figuring out how to run them differently than chisel teeth.
