Switched from a 6-inch to an 8-inch cutterhead on the old Erie dredge last season
We were working a sand and gravel deposit up near the Columbia River, and our production was stuck at about 150 cubic yards an hour. After the swap, which took us a full week of downtime to install, we saw a steady jump to nearly 200 yards an hour within the first month. The bigger head just chewed through the material way faster without bogging down the pump. Has anyone else made a similar upgrade and noticed a big change in how the engine handles the extra load?

That's a solid gain for a week of downtime. We tried a similar jump on a smaller operation years back, and the old diesel engine made noises I didn't think metal could make. It handled it, but I spent the whole season listening to it complain like an old man asked to help move a couch.

Ever wonder if those old engines just get louder on purpose to guilt us? Mine still groans about that one hard pull from like three summers ago.
