John Deere Worksite Pro MH60D Teeth

[tassmannn]

We acquired this mulcher used with about 350 hours on it. Does anyone know if the teeth can be sharpened, or do they need to be replaced? If so, do we do them in phases or all at once? It looks like two large Allen Bolts hold them on, and I think there are 30 total.

Thanks in advance....new to mulcher heads

Well, I will answer my question so everyone can see what I learned. This model has carbide teeth that you replace when they wear out. I guess my next question is, can I replace these teeth with a knife-style?
