“…However, the 40% HB, 40% SB, and 75% SB configurations resulted in a reduction in the drawbar yield (DBY), which was 2.52, 9.89, and 4.39% lower than the treatment without the use of ballast, respectively. What differs from the authors Monteiro, Lanças, and Guerra (2011) when they report that using different ballasting conditions makes it possible to increase the yield in the drawbar.…”

The efficiency of the agricultural tractor can be increased with its assertive operational adequacy, ballasting being one of the fundamental factors for obtaining good performance levels, as it is closely related to energy and operational performance. Thus, the objective of this experiment was to evaluate the effect of hydraulic and solid ballast, under different fractions, on the performance of the agricultural tractor. The banded experiment was conducted in a randomized block design, with the treatments consisting of the five configurations of base mass (B0), B0 + 40% hydraulic (HB 40%), B0 + 40% solid (SB 40%), B0 + 75% hydraulic (HB 75%) and B0 + 75% solid (SB 75%), and four target speeds, with fi ve repetitions, totaling 100 experimental units. To determine the efficiency of the tractor, 4 x 2 AFWD with a rated power of 125.2 kW, the parameters of wheel slip, engine rotation, hourly and specific fuel consumption, power, power, and efficiency in the drawbar, operating speed and thermal efficiency of the engine were monitored. The collected data were subjected to analysis of variance/ when significant, submitted to the Tukey test and regression analysis. The obtained results verified that using the hydraulic ballast in the fraction of 75% presented superiority in the energetic and operational performance, highlighting the engine rotation, force in the drawbar, operational speed, and specific fuel consumption. The increase in operational speed can provide gains in energy and operational efficiency; however, it can generate overload on the engine in some ballast configurations.

“…However, the decrease in SLI when increasing the study speed from 9 to 10 km h -1 is due to the reduction of OS and DBF (KUMAR; NOORI; PANDEY, 2019). These results can be explained by the fact that the skating index is infl uenced by the selected speeds, according to Monteiro, Lanças and Guerra (2011).…”

A potência disponível na barra de tração e na tomada de potência juntamente com a reserva de torque são algumas das principais características a serem analisadas nos tratores agrícolas. Neste sentido, conduziu-se o presente trabalho com o objetivo de avaliar os parâmetros relacionados à potência e ao torque dos tratores agrícolas de pneus comercializados no Brasil em relação a quatro faixas de potência e tipo de tração. O trabalho foi realizado por meio de levantamento das informações em 191 tratores agrícolas, sendo estas obtidas nos catálogos dos espécimes e em alguns casos medidos em loco, quando a informação não estava presente no catálogo. Os parâmetros de potência disponível na tomada de potência e na barra de tração e a reserva de torque foram estimados; sendo que alguns desses parâmetros foram avaliados em diferentes condições de solo. Os dados foram analisados utilizando-se ferramentas da estatística descritiva para comparação dos espécimes. Os tratores superpesados com tração dianteira auxiliar apresentam maior torque disponível na potência nominal do motor, na TDP a 540 rpm e reserva de torque. Os espécimes da faixa de potência média e tração 4x2 TDA têm maior representatividade no mercado nacional, correspondendo a 47 e 79%, respectivamente.
