Final answer:
Sprayer tank agitation and worn nozzles are factors that can impact pesticide spray output, whereas the brand of tractor is generally not a contributing factor.
Step-by-step explanation:
Factors that may impact pesticide spray output include sprayer tank agitation and worn nozzles. The agitation in the tank ensures a uniform mixture of pesticide and prevents settling of the product, which can impact the concentration of the pesticide delivered during spraying.
Worn nozzles can change spray patterns and droplet sizes, leading to inconsistent application rates and potentially reduced efficacy of pesticide treatments.
The brand of tractor used to pull the sprayer generally does not affect the spray output unless the tractor mechanically interfaces with the sprayer in a way that directly affects its operation, which is typically not the case.
Therefore, the factors mentioned are mainly related to the condition and maintenance of the spraying equipment itself rather than the tractor brand.
