Aerial agricultural spraying uses pumps, which are usually powered electrically from the starter/generator. Now I have read, that these pumps can also be powered by an accessory drive hydraulic system. How does that work?

  • $\begingroup$ I’m not clear on the level of detail you are looking for in an answer. At the simplest level an output shaft from the engine that could drive any accessory, (like a generator) would be used instead to power a hydraulic pump. Are you familiar with how hydraulic systems work? If your question was a bit more specific you might get some answers... $\endgroup$ Aug 20 '20 at 16:08
