Rant: People keep running their cutter heads too fast in heavy clay

I was on a job near Baton Rouge last spring, pulling sediment from an old industrial canal. The new guy on the other shift kept the cutter head at full speed, around 22 rpm, thinking it would cut through the thick clay faster. After three days, we had to pull the whole assembly because the teeth were shot and the drive shaft was showing stress cracks. It just grinds the material instead of biting into it. Dropping it to 15 rpm with more down pressure saved us a ton on wear parts. Has anyone else had to retrain crews on this specific point?

Oh man, that's like using a chainsaw to cut butter. You just end up with a greasy mess and a broken chain. Some guys see a tough material and their only idea is to crank everything to max, like it's a video game power-up. It's a slow, expensive way to learn that finesse beats brute force every time with that sticky stuff.

Ugh, my dad tried that with a frozen turkey once.

Maybe the real trick is treating it like cold honey instead of steel.
