A multiple blade agricultural grader has a frame (20) that surrounds the wheels (21) of a farm tractor and can be retracted from the ground under the tractor for transport purposes or lowered to the ground for grading. The frame has a number of longitudinal arms (22) arranged in parallel from the front to the back of the tractor and side arms arranged at an angle (30) to guide the remainder of gravel toward the centre of a road to be graded and into potholes in the road. A front arm (28) is oriented at 30 degrees toward the centre of the road and includes a cutting edge (38), an overflow (34,36) and a hoisting eye (54) with chain (56). Secondary arms (40) are also equipped with blades that guide gravel from front to rear. A terminal arm consists of an angle blade (48) suspended in the centre by a pivot (50) connected to the rear of the tractor by a hydraulic cylinder (58). Its ends have bails (52) that slide in the side arms.
Une niveleuse multilame agricole a un cadre (20) entourant les roues (21) d'un tracteur de ferme et peut être rétractée du sol sous le tracteur pour les fins du transport ou abaissée contre le sol pour les fins du nivelage. Le cadre a un nombre de longerons longitudinaux (22) disposés en parallèle de l'avant vers l'arrière du tracteur et des longerons transversaux disposés à angle (30) pour guider les surplus de gravier vers le centre d'une route à niveler et vers des trous de poule de la route. Un longeron frontal (28) est orienté à 30 degrés vers le centre de la route et il comprend une lame d'usure (38), des excédents (34,36) et un oeil de levage (54) par une chaîne (56). Des longerons secondaires (40) aussi porteurs de lames guident le gravier de l'avant à l'arrière. Un longeron terminal est fait d'une lame orientable (48) suspendue au centre par un pivot (50) relié à l'arrière du tracteur par un vérin hydraulique (58). Ses bouts ont des étriers (52) qui coulissent dans les longerons des côtés.
