A refined arrangement for the highlift adjusting mechanism for the blade of a motor grader is disclosed. The arrangement uses the traditional twin highlift cylinders connected to the motor grader by means of bell cranks. A rigid link member joins lower ends of the bell cranks and includes a number of locking ports therein. The link member is pivotally connected to the bell cranks by means of a specialized arrangement which additionally defines a further locking port. In the preferred form, the link member is secured to the bell cranks by pin members which include a cavity in one end thereof sized to receive the locking pin. With this arrangement, the bell cranks can be maintained closer to the frame of the grader and improved visibility is achieved.
