Abstract: A rotating mechanical apparatus, such as would be used in a reel mower assembly, comprises a drive member rotatably mounted in a frame about a shaft axis. The drive member has a drive face. A driven member has a driven shaft rotatably supported in the frame about the shaft axis, and a driven face. A projection extends outward from one of the drive face and the driven face and into a corresponding recess in the other. Magnets force the drive face against the driven face such that the driven shaft rotates with the drive member. One of the drive face and the driven face are movable along the shaft axis to disengage the projection from the recess. A height adjustment mechanism moves ground rollers closer together or farther apart to vary cutting height.

Abstract: A rotating mechanical apparatus, such as would be used in a reel mower assembly, comprises a drive member rotatably mounted in a frame about a shaft axis. The drive member has a drive face oriented perpendicular to the shaft axis. A driven member has a driven shaft rotatably supported in the frame about the shaft axis, and a driven face oriented parallel to and bearing against the drive face. A bulb extends outward from one of the drive face and the driven face and into a corresponding recess in the other. Magnets force the drive face to bear against the driven face such that the driven shaft rotates with the drive member. One of the drive face and the driven face are movable along the shaft axis to disengage the bulb from the recess. A height adjustment mechanism moves ground rollers closer together or farther apart to vary cutting height.

Abstract: A bed knife for a mower includes a cutting implement for cutting a material. The bed knife includes a mounting portion that mounts to the mower, and a cutting area at which the cutting implement cooperates with the bed knife to cut the material. The bed knife further includes a serrated portion including a plurality of teeth.
