A cutterhead for cutting aquatic vegetation, includes a cutterhead shroud, stationary teeth secured to the shroud, and a drum rotatably mounted within the shroud and bearing a flight of vanes cooperating with the teeth to cut vegetation. In accordance with the non-binding aspect of the cutterhead, each vane has an edge that rises gradually from a trailing end adjacent (during drum rotation) to a stationary tooth, to provide a clearance area adjacent the vane into which a respective tooth may be deflected during cutting without impinging upon an associated vane, and thus without causing binding of the cutterhead in the event of such deflection. Each vane may have a curvilinear edge extending from its cutting end to a surface of the drum at its trailing end. The edge defines a two-dimensional profile having a trailing end tangent forming an angle of not more than 70 degrees with the drum.
