We switched from a 6-inch to an 8-inch cutter head on our old dredge in the Sacramento River delta last season. The silt load we moved in a day basically doubled.

We saw the same jump on the Columbia with a wider head, but the extra wear on the pump was a real trade-off.

Yeah, that's the exact problem we ran into. @shanewells, how long did it take before you started seeing the pump issues? We got maybe two months of great flow before the extra strain really showed up. It felt like a constant fix one thing, break another situation. Not worth the trade off in my book.
