    Abstract: An adjusting device for the main shield of a grader in which two lifting cylinder, a sideways adjusting cylinder and two pivot arms interconnected by an arresting bridge for actuating the main shield are by the arresting bridge linked to a bridge frame of the grader which bridge frame has a rectangular cross section. Each of the two pivot arms are arranged for pivoting about two joints while one of the pivot arms has its free end provided with fulcrums arranged asymmetrically with regard to the vertical axis of symmetry for establishing linkage connection with one lifting cylinder and a sideways adjusting cylinder. The other one of the two pivot arms is at its free ends provided with a fulcrum for establishing linkage connection with the other lifting cylinder. The arrangement is such that one joint each serves for journalling the pivot arms on a front wall fixedly connected to a frame member of the grader and to the back wall likewise fixedly connected to the frame member, whereas another joint edge serves for journalling the pivot arms on the movable arresting bridge. The quadrangular joint structure comprising the above mentioned four joints is non-symmetrically arranged with regard to the axis of symmetry of the vehicle frame member and is displaceably arranged in the vertical plane.

    Abstract: A motor grader including a main frame mounted on steerable wheels, a drawbar frame mounted on the main frame, a working implement carried by a circle gear rotatably mounted on the drawbar frame and a hydraulic control circuit is described. An improvement in the control of the working implement is disclosed in which continuous downward force is exerted on the circle gear at all times during operation by hydraulic rams. Preferred embodiments of the invention are described wherein the force is exerted by hydraulic means including wear surfaces in contact with the circle gear and wherein the hydraulic control circuit is adapted to provide automatic operation.

    Abstract: A motor grader has a circle with integral, depending arms at the rear, and the lower ends of the arms extend forwardly so that blade mountings, comprising bearing housings pivoted at their lower ends to the extremities of the arms, extend upwardly in very close proximity to the fronts of the arms. Two hydraulic cylinder and piston units for tilting the blade mountings are carried in sleeves which are integral with and between the arms, directly behind the upper end portions of the blade mountings, which permits the use of very short stroke pistons that are well protected from damage by earth and rocks piled up by the blade. In addition the units are mounted in spherical bearing and socket means for limited universal movement within the sleeves. Further, the piston rods extend along shallow chords of a circle struck about the pivots which mount the bearing housings, so working forces are applied substantially axially to the piston rods in all positions of the bearing housings.

    Abstract: A soil tilling machine comprising a ploughshare assembly supported on a supporting member between the wheel axles for rotation, and capable of being locked in an adjusted angular position in relation to the longitudinal axis of the machine. The supporting member is pivotally attached at its front end to a frame of the machine so as to be capable of being adjusted in elevation and in lateral tilted position by means of hydraulic cylinders which are connected to the free rear end of the supporting member at laterally offset sides thereof and to a suspension body which is longitudinally displaceable on the frame.
