Cutterhead teeth wore out in 3 weeks, shop said it was my swing speed
Ran a job up near Green Bay clearing out a silted slip, maybe 40 hours of actual cutting. Pulled the cutterhead for inspection and the teeth look like they went through a rock tumbler. Shop foreman said I was swinging too fast and letting the head bounce instead of letting it bite. Never had that issue in 10 years running the same type of setup. Anyone else get told this? Should I drop down to a slower swing and just eat the longer cycle time, or is the foreman blowing smoke because they want to sell me harder teeth?

The "letting the head bounce" part doesn't hold up. Bounce comes from the head not being balanced or the pump pressure dropping, not from swing speed by itself. Slower swing on a silt job usually makes things worse, because the head sits in the cut longer and grinds instead of cutting, and grinding is what eats teeth. We ran silt with a lot of grit in it and that stuff is flat out abrasive, 40 hours of it can do real damage no matter how you swing. So I'd check your pump and your tooth holders first, and if that foreman can't explain the bounce with numbers, he's probably just selling teeth.
