A hydraulic support with wheels for a snowplough; it attaches to the structure of a snowblower, and is used to raise the snowplough to a certain height off the ground. The system comprises a dual-action cylinder, attached to the rear of the structure with an angle plate. The cylinder rod forms a ball joint with the end of a pivoting arm which also attaches to the angle plate, the ball joint forming the apex of an acute angle. The end of the pivoting arm traces a circle arc. Double wheels are located at the ball joint and follow the circle arc when the ball joint is pushed by the cylinder rod, the wheels thus entering into contact with the ground, to raise the snowblower structure.

Un support hydraulique avec roues pour chasse-neige, se fixant sur le caisson d'une souffleuse, pour le soulever à une certaine hauteur du niveau du sol. Ce système comprend un cylindre à double action, fixé a l'arrière du caisson, à l'aide de cornière. La tige du cylindre forme une rotule avec l'extrémité d'un bras pivotant qui s'attache aussi sur la cornière, la rotule formant l'apex d'un angle aigu. L'extrémité du bras pivotant trace un arc de cercle. Des roues doubles sont situées au niveau de la rotule et suivent l'arc de cercle quand la rotule est poussée par la tige du cylindre, les roues prenant ainsi contact avec le sol, pour soulever le caisson de la souffleuse.
