Boom support structure for a sprayer including a boom center frame supported for rocking both about a fore-and-aft extending axis and an upright axis by a torsional pendulum structure to isolate the boom from the sprayer frame movement in both the roll and yaw directions thereby reducing fluctuations in the relative velocities of the boom ends as the sprayer moves over irregular ground surfaces. The pendulum structure and guide structure connected between the boom center frame and the boom support maintain the boom generally parallel to the ground even on hillsides without need for additional latching mechanisms.

A boom support for a framed vehicle adapted for forward movement over the ground, comprising: a support frame connected to the vehicle frame; a boom frame; and means for supporting the boom frame from the support frame including an upright torsional link having an axis and means connecting one end of the torsional link to the support frame for securing said one end against rotation about the link axis, and means connecting the opposite end of the link to the boom frame, the link yieldingly biasing the boom frame to a normal operating position while accommodating rocking movement of the boom frame from the operating position about the link axis for isolating vehicle yaw from the boom frame.
