Technical criteria for the selection of self-propelled sprayers available in the Brazilian market

摘要

In recent years the offer of self-propelled sprayers in the Brazilian market increased mainly to supply the demand of farmers who own large areas where there are a high operational pace requirement. In this research the different kinds of transmissions, tank capacity of spray mix, width of bars and clearance, which are considered important technical criteria, were evaluated according to nominal engine power. Technical information of 41 self-propelled sprayer models commercialized in Brazilian market were used. As result, sprayers were classified in five classes, according to the engine power. It was verified that, with the increase of power, the sprayers are equipped with hydrostatic transmission and the tank capacity of spray mix are higher.
