    • The present invention relates to a boom structure for an agricultural implement (1), wherein a pivot link connects a boom section (20) with a frame (10), and actuator means (18) being capable of generating a desired pivoting of the boom section (20) about an axis (A). The pivot link is characterized by comprising a first link part (40) which is connected with the actuator means (18), and which is pivotally secured to the frame (10) to be capable of pivoting about said pivot axis (A), a second link part (50) which is connected with the boom section (20), and which is pivotally secured to the frame (10) to be capable of pivoting about said pivot axis (A), and shock absorbing means (44, 44′, 46, 46′) arranged between the first link part (40) and the second link part (50), said pivot link (30) being moreover adapted, by activation of the actuator means (18), to generate said desired pivoting of the boom section (20) by pivoting about the pivoting axis (A) of the first link part (40) and the second link part (50).
