Abstract
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.
