  • Method of installing plates on blade of plow or grader
    Patent number: 6654998
    Abstract: A cart is configured to handle replaceable plates used on the blade of a plow or grader. The cart includes a wheeled frame and a plate holder configured to support the plate lengthwise in a generally upright orientation. The plate holder is supported on the frame by a parallelogram linkage that permits adjustment of the plate holder, and thereby the plate carried by the holder, without varying the orientation of these components. An inventive plate installation method is also disclosed. The method involves placing at least one plate on the height-adjustable plate holder carried on the mobile frame. The attachment holes defined in the plate are then aligned with the attachment holes defined in the blade.
