Which of the following is a disadvantage of high pressure hydraulic sprayers?

• A. Tend to be heavy and costly
• B. They are lightweight
• C. They require minimal water
• D. They are easy to maneuver in dense vegetation

Answer: (A)

High pressure hydraulic sprayers deliver liquid at very high pressure to produce fine droplets for better coverage. That capability comes with trade-offs: the pump, pressure chamber, and robust frame required for safe operation add substantial weight, and the higher-quality components and safety features drive up cost. Because of these factors, they tend to be heavier and more expensive than lower-pressure or more simple sprayers. The other statements describe traits that would be advantages (being lightweight, needing minimal water, easy to maneuver in dense vegetation), which do not reflect the typical drawbacks of high-pressure systems.
