Agricultural machine (10) to rake a mass of hay, or other agricultural product, comprising at least a trailer-mounted frame (11), and an arm (15a, 15b) on which a plurality of operating tools (12) are rotatably mounted. The arm (15a, 15b) is constrained to the frame (11) so as to selectively move between a first operating condition in which the operating tools (12) are in cooperation with the ground, and a second inactive condition in which the operating tools (12) are raised from the ground in a position substantially parallel to the ground itself. The agricultural machine (10) comprises articulation members, interposed between the frame (11) and the arm (15a, 15b) and comprising a first positioning portion (19a) attached to the frame (11) and a second positioning portion (19b) to which the arm (15a, 15b) is constrained. The first positioning portion (19a) and the second positioning portion (19b) are pivoted with respect to each other by means of an articulation pin (14), in order to move the arm (15a, 15b) between the two conditions, operating and inactive. |
