ABSTRACT:
An articulating and locking mechanism of agricultural implement chassis is disclosed, intended for disc harrows and other implements with great working width, which are characterized by articulation to reduce the total width so as to facilitate transportation and storage, constituted of a main structure or chassis (1), central disc gang chassis (2), lateral and articulating disc gang chassis (3), with arrangements of vertical plates or extensions (4and5) welded and joined by shafts (6) for articulation by means of hydraulic cylinders (7), equipped with locking mechanism made up of hydraulic cylinders (8), locking and unlocking actuators (9, 9A), locks (12, 12A), coupling shafts (13, 13A) inserted in sleeves (14, 14A) and joined to the vertical closure plates (15) of the inner ends of the articulating chassis (3). Locking flanges (17) welded to the central chassis (2) form a quick closing action with the locks (12, 12A) providing rigidity in the locking between said rigid and articulating chassis during the implement's field operation.
