Pro tip: check your cutter head wear with a simple tape measure trick I read about in an old dredging manual
I was flipping through a 1990s manual from the US Army Corps of Engineers library online and saw a section on cutter head maintenance. It said you can measure wear on the teeth and shrouds just by checking the diameter with a tape measure across the cutting circle. If it's worn down more than 3 inches from the original spec, you're losing serious efficiency and need to schedule a rebuild. I tried it on our 16-inch cutter suction dredge and found we were 4 inches down on one side. No wonder our production rate felt off. Has anyone else used this method or have a different wear check they swear by?

Did they mention how often you're supposed to check it, or is it just a "when production feels off" kind of thing?

Ever notice how this "check it when it feels wrong" logic is everywhere now? My landlord says to call about the heat only when the apartment gets cold, not for a yearly check. It's just passing the responsibility onto us to notice the problem first. They want us to do the monitoring so they don't have to pay for a real schedule.

Was there any talk about setting up a basic schedule, like maybe a quick look at the start of each shift? I feel like just going by "feel" is how small problems get missed until they turn into a big stop.

Actually the manual said to check it monthly, not just when it feels off.
