Resumo: ABSTRACT: In a tractor, the transmission system transmits the power generated in the engine to the driving wheels, hydraulic systems, and power take-off (PTO). There are several types of transmission systems available in the Brazilian market ranging from the simplest to the most advanced. Therefore, the objective of this study was to verify the different types of transmission systems present in 228 models of agricultural tractors produced and marketed in Brazil during 2019. The tractor models were grouped based on the engine power and the transmission systems were classified as sliding, partially synchronized, synchronized, semi powershift, full powershift, and continuously variable transmission (CVT). According to this classification, it was found that most tractors belonged to Class III (51.5-73.5 kW) with 66 models in total. However, even with continuous modernization in this field and with tractors becoming increasingly independent from the operator, 66% of transmission systems are still mechanical. However, CVT systems, which are available only in tractors with an engine power above 117.7 kW, are expected to be equipped on less powerful tractors in the coming decades.
