A suspension device (1; 100) for a boom (2) of a product spraying agricultural appliance comprises elements for mounting the boom (2) on the chassis (1a; 101a) of the appliance. The suspension device (1; 100) comprises a means (7, 8; 107, 108, 115) to dampen the movements of the boom (2) and adjusting members (7, 8; 107, 108) capable of acting on the elements for mounting the boom (2). The adjusting members vary the position of the instantaneous centre of rotation (CIR) relative to its centre of gravity (CG), preferably by modifying the spacing between the centre of gravity (CG) and the instantaneous centre of rotation (CIR) located higher than the centre of gravity (CG).
