Abstract (en)
[origin: WO2022137141A1] Grader Apparatus for attachment (4) to a vehicle has a main body portion (2) coupled to a blade body portion (8) by multiple linkages. These include primary load bearing links (15, 17) which connect (16) to the blade portion (8) aligned in a vertical z-axis allows rotation of the blade portion (8) thereabout. Adjustable length actuators (18) allow rotational yaw control about the z-axis. Adjustable roll actuators (19) connect between an extension (3) of the main body portion (2) and the blade body portion (8) to control its elevation and roll angle. Other embodiments allow lateral shifting of the blade body portion (8), and include an improved slope sensor catering for yaw with roll combinations.
