Old timer told me to slow down my cutterhead speed on a tough job - changed my whole approach

I was running a 12 inch cutterhead on a sandy channel near Baton Rouge last month and kept burning through teeth every 4 hours. This retired guy, Jim, who used to run a dredge on the Mississippi back in the 80s, told me to drop my RPM from 180 to 130 and just let the material flow. I thought he was crazy but I tried it on my next shift and holy cow, I got almost 11 hours out of that same set of teeth before needing a swap. Has anyone else gotten advice from an old hand that actually worked way better than what the manual says?

Jim out at the sand pit last month told me the same thing about slowing down my drum speed when the material got heavy. I was fighting it and burning through wear parts like crazy. He just said "let the machine eat at its own pace." It's funny how that advice applies to so much more than just machinery. I've started noticing that pushing harder on anything from yard work to even cooking dinner just makes things worse, going slower actually gets you farther in the long run.

Wait wait wait... Jim from the sand pit? The Jim with the missing two fingers on his left hand? I thought that guy retired like 3 years ago after the conveyor belt incident. Him still being out there giving advice is WILD to me, I figured he would have hung it up for good after that mess. But honestly that advice about letting the machine eat at its own pace is pure gold, I've watched guys burn through thousands of dollars in crusher parts just because they wouldn't back off the throttle when things got chunky. Its crazy how that lesson carries over to everything else in life too, I catch myself trying to force things at work and at home and always end up regretting it.

Respectfully gotta push back on that one. Honestly, the whole "let the machine eat at its own pace" thing works great in theory, but I've seen guys take it way too far and end up with plugged chutes and downtime that costs way more than a few wear parts. Tbh, sometimes you gotta give it a little extra throttle to keep things moving through, especially with wet material that likes to pack up. Ngl, I've been in situations where letting it eat slow just meant it stopped eating altogether and then you're pulling chunks out by hand for an hour. That advice from Jim probably worked in his day with older machines, but modern crushers can handle some aggression if you know what you're doing.
