ABSTRACT:
A head section for a rotary cutting device includes a body portion that includes a blade passage defined between a blade entrance opening and a blade exit opening. A blade fastening mechanism is positioned in the blade passage and includes a blade engaging member. The blade engaging member is biased by a biasing mechanism to extend across the blade passage at a blade install position. The blade engaging member is movable against the bias to clear the blade passage. A blade having a mount aperture proximate an insertion end thereof is secured to the body portion when the mount aperture occupies the blade mount position and the blade engaging member extends through the mount aperture. The blade can be installed in and removed from the head section without tools, simply by advancing the blade through the blade passage.
