(under subclass 781) Apparatus in which the scraper is adjustably mounted on the vehicle frame and in which there is a means for facilitating the adjustment by at least partially counterbalancing the weight of the scraper.
(1) Note. Included under this definition is a counterbalance means which more than compensates for the weight of the scraper and is the sole means for moving the scraper to an
adjusted position against the force of gravity.
