  • Patent number: 7225520
    Abstract: A cutting edge cart is disclosed that provides an improved means for replacing the replaceable cutting edges on bladed equipment such as road graders and snow plow. The cart allows a single user to retrieve, transport, and position a replacement cutting edge relative to a mold board of the bladed equipment. Generally, the cart contains a frame, two or more transport assemblies attached to the frame, such as wheels, a movable carrier assembly that contains a cutting edge support assembly, and an adjuster. The adjuster is operable to move the carrier assembly between first and second positions relative to the frame allowing the vertical position of a supported cutting edge to be adjusted. The frame and transport assemblies are disposed such that the cart may be rotated or pivoted from a first generally vertical position to a second generally horizontal position.
