Boom acceleration and height effects on spray deposit were determined for distinctly different track conditions,droplet spectra, and sprayer tank loads using an instrumented self-propelled sprayer with a 27 m boom at 12.8 km/h. Trackconfigurations were: smooth, a 20 cm high bump, and a 20 cm high bump and an opposing 20 cm deep dip. Droplet spectraincluded 255 and 588 .m volume median diameters (Dv0.5) as determined by laser diffraction. Sprayer tank loads were eitherhalf capacity or empty. Results indicated three-dimension accelerations ranging from 1.8 to -1.1 g, 14.3 to -6.7 g, and 20.7to -11.0 g and boom end height effects ranging from 2.0 to 1.2 m, 2.6 to 0.5 m, and 3.5 to 0.4 m for smooth, bump, and bumpand dip tracks, respectively. Small droplets of 255 .m (Dv0.5) resulted in a spray coverage range (with maximum coefficientof variation, CV) from 11% to 22% (55%). Small droplets produced Pearson correlation coefficients between coverage andlocalized, instantaneous boom height ranging from -0.40 to -0.58. Large droplets of 588 .m (Dv0.5) resulted in a spraycoverage range (with maximum CV) from 9% to 18% (39%). Large droplet Pearson correlation coefficients between coverageand localized, instantaneous boom height ranged from 0.49 to -0.62. Spray coverage significantly (P
