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.
