Question

Which agricultural operation involves the use of mechanical devices such as jet sprays?

Answer 1

Cleaning operations

Jet sprays are high pressure water sprayers used for cleaning on farms (and in various other industries).  When cleaning livestock barns or grain silos or agricultural equipment, jet sprays are about the only efficient way to go about cleaning processes.  Imagine having to do heavy-duty cleaning before the application of industrial technologies (like high pressure sprayers) to farming operations!
