  • Mower blade
    Patent number: 4375148
    Abstract: An improved blade for a rotary lawn mower includes cutting elements which are removably attached to a base member. The removable elements may be made of a higher quality steel than the base member and may be easily removed for sharpening or merely replaced with a new element. A removable element is held in the base member by means of a wedged slot which cooperates with a wedged part of the shank of the removable cutting element, while a notch in the base member serves to hold the back of the blade.
