ABSTRACT:
A hydraulic linkage for tractors and other vehicles in which loader arms are turnable upwardly and downwardly relative to a fixed frame part by first and second hydraulic rams. As seen in side elevation, the pivot axis of said arms and pivotal connections of the first ram(s) are at the corners of a triangle and a pivotal connection between the arms and apparatus coupled thereto and pivotal connections of the second ram(s) are at the corners of a second and separate triangle. The first and second rams are operatively interconnected in such a way that displacement of the piston of the first ram or rams causes hydraulic pressure medium to flow to the second ram or rams and effect piston displacement therein, or vice versa.
