Thought those new polymer cutter heads were just marketing fluff
My crew on the Lake Erie project last year got a set to test. I figured they'd crack in the cold or wear down fast. Ran them for a full 8 week season moving gravel and clay. Zero breaks, and wear was maybe 15% less than our steel ones. The weight savings on the crane hook was real. Anyone run these on a bigger scale than a test?

Honestly that tracks with what I heard from a guy on a dredging crew. They said the real win wasn't just the wear, it was how they didn't get all gunked up in wet clay like the old steel ones. Made cleanup way faster. Tbh I'd be worried about running them over real jagged rock though.

Ever see those big poly skids on mining gear? They take way more abuse than you'd guess. The flex actually helps them slide over sharp edges instead of catching.

Yeah but @robertlane, that flex you mentioned... doesn't that just mean they bend out of shape easier under a real load?
