Abstract: A rotary cutter head includes integral clamping members for releasably securing cutting blades in recesses formed in the cutter head. Each clamping member is formed with a free end portion which defines one side of the recess. An end of the clamping member located oppositely of the free end portion is integrally connected to the cutter head and defines a resilient hinge portion. The free end portion is resiliently biased by the integral hinge portion to a position which allows the blade to be slidably received in the recess. Threaded fasteners are operable to cause the free end portion to pivot about the hinge portion and to drive the free end portion toward an oppositely located side of the recess so as to clamp the blade in the recess.
