  • Method of constructing a bed knife assembly for reel mowers
    Patent number: 6618925
    Abstract: A method of constructing a bed knife blade assembly for a reel-type lawn mower having a frame rotatably supporting a cutting reel. The bed knife blade assembly comprises a clamp plate having a flange with a locking surface, and a blade insert having a tab cooperating with the locking surface to restrict movement of the blade insert relative to the clamp plate. The clamp plate is adapted to be coupled to the frame such that the flange biasedly engages the tab to further restrict movement of the blade insert relative to the clamp plate.
