A dynamic model has been developed that represents a trailed field sprayer with a transversly mounted cylindrical tank. Water slosh and tire deformation were accounted for in the model. A pendulum has been incorporated into the tank element of the model to represent water slosh. The model was validated in the laboratory by dropping one side of the sprayer and filming the motion of the sprayer boom. A Global Distribution Index (GDI) was defined based on the predicted distribution of spray. By comparing the GDI at various tank water levels, a 42% improvement in the distribution of spray was shown as the sprayer tank emptied.
