ABSTRACT:
The specification discloses a new blade positioning apparatus for use in motor graders, that provides improved visibility and allows the operator to easily control the elevation, transverse inclination, and position of the scraper blade beneath the machine. The device comprises a transverse "W" shaped beam pivotally mounted to the upper surface of the support frame of the grader to allow partial rotation of the beam about the main frame. A link member passes beneath the frame of the grader and is secured to the beam member, such that the beam and link members encircle the frame. The link member cooperates with a releasable lock mechanism for securing the beam member at selected adjusted positions relative to the support frame. According to a preferred aspect of the invention, the lock mechanism includes a bar lock pivoted at one end beneath the frame of the grader and is received in tapered notches provided in the link. An over-center locking linkage arrangement is provided for moving the free end of the bar lock from a locked position to a free position for adjusting of the beam relative to the frame.
