Just found out my cutterhead was 30% worn and I had no clue

I was checking the manual for something else and stumbled on the wear limits for the teeth on my Ellicott 370. Measured it up and three of them were past the spec, been running like that for months probably. How often do you guys actually pull the specs and check against the book?

idk, i think you guys are overthinking it. i mean, those wear specs are just guidelines, right? the manual says one thing but real world conditions are totally different. maybe it's just me but i've run teeth way past what the book says and still got good production. three teeth being a bit worn isn't gonna throw the whole head out of balance unless you're running some super precise operation. most of the time you can feel when it's actually bad, the vibration and slow cutting are pretty obvious. checking every time you pull the head seems like a lot of extra work for not much gain.

Man, that's rough... I check mine every couple months but honestly I think most people just run 'em until they start cutting bad. Three teeth past spec is way more than I'd be comfortable with though... you probably lost a lot of efficiency without even knowing it.

Ah, that's a good find but I've got to gently push back on something Emma said there. Actually @emma_garcia, it's not quite three teeth past spec - a cutterhead has more than that, and if three are worn past the limit you're already into significant wear patterns that throw the whole head out of balance. I check mine every time I pull the head for maintenance, maybe twice a season, and I use a basic gauge from the manufacturer. The real trick is to track which teeth wear fastest so you can rotate them before you lose efficiency. Most guys never look until they feel vibration or see slow cutting, and by then you've wasted a lot of fuel.
