1. A boom mounting assembly for attachment to an agricultural application machine, the assembly comprising a boom support frame which is suspended from a primary frame mounted to a chassis, the boom support frame comprising a transverse beam for supporting an intermediate section of a fluid application boom and being suspended so as to allow yaw and pitch of the boom support frame relative to the primary frame, the assembly further comprising a first and a second damper each connected between the primary frame and the boom support frame at a position spaced from the transverse center of the assembly, wherein damping of pitch and asymmetrical yaw movement of the transverse beam away from a neutral position is controlled by the first and second dampers;
the boom mounting assembly further comprising a fifth and sixth damper to damp symmetrical yaw movement of the fluid application boom relative to the support frame, wherein said fifth and sixth damper are each connected between the boom support frame and a respective symmetrical yaw linkage which is connected to a respective half of the boom; and wherein each of the first and second dampers is connected between the primary frame and a respective elbow bracket which is pivotally attached to the primary frame, and wherein each bracket is connected to a respective end of the transverse beam by a strut so that fore and aft movement of the beam is translated into at least partial vertical force upon the first and second dampers. |
