What is the primary equipment used for hydraulic agitation in spray tanks?

The primary equipment used for hydraulic agitation in spray tanks is a shaft with paddles. This mechanism is crucial because it helps to keep the spray solution uniformly mixed, ensuring that the pesticide or herbicide is evenly distributed within the tank. Proper agitation prevents the active ingredients from settling at the bottom of the tank, which can lead to ineffective application and inconsistent results in pest control.

The design of the shaft with paddles allows it to draw spray solution from different depths as it spins, effectively mixing the liquid and ensuring that the concentration remains consistent throughout the application process. This is essential because variations in concentration can affect the efficacy of the chemicals being applied.

Understanding that pumps, nozzles, and filters serve different roles in the spraying process is important. Pumps are used primarily to move the liquid from the tank through the system, nozzles facilitate the application of the spray to the target, and filters prevent debris from clogging the system. However, none of these components fulfill the specific function of agitation within the spray tank like the shaft with paddles does.
