Sucked a rock through the cutterhead on the Mississippi last summer

I was working a dredge near Baton Rouge on a channel maintenance job, maybe 3 miles south of the port. Everything was running smooth for about 6 hours, then I heard this grinding noise that felt like it was coming from inside my skull. The cutterhead just locked up solid, and I mean dead stop. Turns out a chunk of limestone about the size of a football got sucked into the suction side and jammed everything. I had to shut down the whole rig for 8 hours, pull the cutterhead, and cut that rock out with a torch while standing in mud up to my knees. Cost the company around $4,000 in downtime and a new set of teeth. Has anyone else dealt with getting big debris through your pump when the spoiler bar is supposed to catch it?

Sounds like the spoiler bar was taking a nap that day. Bet that rock is still sitting in someone's garage as a souvenir.

Strange how we all hold onto random stuff like that. Wonder if the universe throws those moments at us just to see what we'll do with them lol.
