The spray linkage comprises a support (16) and a central frame (18) fastened pivotably to the support (16), the central frame (18) being pivotable on both sides relative to the support (16) from a neutral position about a substantially vertically aligned oscillating axis (32), and at least one hydraulic cylinder (34, 36) is arranged, which at one end is fastened in an articulated manner to the support (16) and at the other end in an articulated manner to the central frame (18). In order to achieve improved and simplified damping of the spray linkage (10) during oscillating movements, it is proposed that the at least first hydraulic cylinder (34, 36) has a first and a second hydraulic chamber (44, 46, 48, 50), a first hydraulic line (52, 54) is provided which discharges into the first hydraulic chamber (44, 46) and a second hydraulic line (54, 52) is provided which discharges into the second hydraulic chamber (48, 50) , means (58, 60, 62, 64) being provided via which the one hydraulic flow from a hydraulic chamber (44, 46, 48, 50) is throttled and a hydraulic flow into a hydraulic chamber (44, 46, 48, 50) takes place in a substantially unthrottled manner.
