<p>The crop-spraying apparatus set forth herein not only delivers a jet or jets swung through an arc of 180 DEG or more, but also incorporates means for delivering a secondary, or auxillary jet covering a more central and acute arc, and swinging through a plane beneath the main jets at considerably greater frequency. Hose lines (6, 7, 8) supplying liquid to the jet-nozzles (12, 13, 14) are kept parallel, basically speaking, and are suspended in the vertical from a manifold (2) this set at a fixed distance from the main body (25) of the apparatus, and being the route through which liquid for spraying is pumped to the nozzles (12, 13, 14).</p> |
