La présente invention concerne un stabilisateur configuré de sorte que, lorsqu'un patin stabilisateur avec une surface antidérapante est tourné jusqu'à une position dans laquelle la surface antidérapante peut entrer en prise avec le sol, le patin stabilisateur est empêché de tourner. Un stabilisateur (30) est pourvu d'un support (31) fixé à un corps de machine, d'un corps de pied (32) dont une extrémité est supportée de façon rotative par le support (31), d'un vérin hydraulique (33) qui sert d'actionneur et est monté entre le support (31) et le corps de pied (32), et d'un patin stabilisateur (34) supporté de façon rotative à l'autre extrémité du corps de pied (32). Un mécanisme anti-rotation (60) destiné à empêcher la rotation du patin stabilisateur (34) est monté sur une extrémité d'un arbre de support (38) qui est prévu à l'autre extrémité du corps de pied (32) et qui supporte de façon rotative le corps de corps (32) et le vérin hydraulique (33).
