“…Similar results were obtained by Estrada et al (2016) when evaluating the performance of a diesel engine using different hydrated ethanol mixtures. Martins et al (2018) measured the energy performance of an agricultural tractor using an offset disk harrow and found no significant differences in DF, corroborating the present study. Tabile et al (2009) evaluated fuel consumption with different castor bean biodiesel mixtures and found that SFC was 358 g kW h -1 and DF was 23 kN, which are similar to the results of the present study.…”

The operational performance of the agricultural tractor can be increased by adjusting parameters such as tire inflation pressure, axle mass distribution and gauge opening, which is a very divergent factor in controlled-traffic production. The objective of the experiment was to measure the energy performance of a 93 kW agricultural tractor in intermediate grading operation in two slopes (flat and sloping) and three gauge configurations (closed, intermediate and open) in mobilized soil. Energy performance was determined from the following parameters: slip, engine speed, actual effective speed, hourly and specific fuel consumption; strength, power and performance on the drawbar. Turbo pressure and temperature monitoring was also performed at six different engine points. The experiment was conducted in double factorial arrangement (2 slopes and 3 gauges), with four replications, totaling 24 plots. Data were analyzed for normality and homoscedasticity of the residues, after ANOVA and when significant, the means test. Tilts and tire gauges did not differ statistically, so it can be concluded that depending on the operation do not interfere with operating performance.

“…Engenharia Agrícola,Jaboticabal,v.40,n.5 The parameters HFC, OS, DBP, DBE, and EL increased as the used gear increased, whereas the parameter ES showed the opposite behavior. Martins et al (2018) analyzed the energy optimization of agricultural tractors and found similar results to the parameters OS, DBP, and DBE. The high number of the selected gear provided a higher effective speed and, therefore, higher OS, DBP, DBE, and EL and hence higher HFC, reducing ES.…”

OPERATIONAL AND ENERGY PERFORMANCE OF 250 kW DOUBLE WHEELED VERSUS RUBBER HALF-TRACKED TRACTORS IN THE SOYBEAN SOWING

et al. 2020

The technological innovation in agriculture seeks to improve the performance of mechanized assemblies and, currently, rubber half-tracks are a valuable solution for agricultural tractors, combining traction performance and less soil compaction. The objective of the experiment was to evaluate the operational and energy performance of double wheeled versus rubber half-tracked agricultural tractors in the soybean sowing. The experiment was conducted in a strip-plot design with a double factorial arrangement (2×3). The first factor consisted of a tractor with double wheels on the front and rear axles versus a tractor with single wheels on the front axle and rubber half-tracks on the rear axle, while the second factor consisted of three different gears, with five replications, totaling 30 experimental units. The collected data were subjected to analysis of variance and, when significant, to the Tukey test. The sowing operation carried out with the halftracked tractor was the most efficient in most of the analyzed parameters, allowing higher operational and energy efficiency in the soybean sowing.

“…A utilização da mecanização agrícola tornou mais eficiente diversas operações, sendo o trator a principal máquina utilizada na realização das atividades agrícolas permitindo assim a realização de práticas de cultivo mais eficientes (Martins et al, 2018). Conforme (Pinto et al, 2020) o trator é uma máquina auto propelida que permite a realização de práticas de cultivo mais eficientes, dentro do período considerado ótimo para as culturas.…”

O uso da mecanização agrícola permitiu a realização de práticas de cultivo mais eficientes nas lavouras. Objetivou-se avaliar a qualidade da operação de preparo do solo com grade aradora em três velocidades de deslocamento utilizando o Controle Estatístico de Processos (CEP). As velocidades utilizadas foram 3, 4 e 5 km h-1. O trator utilizado foi da marca New Holland, modelo 7630, com potência de 80 kW (108 cv) no motor, acoplado a grade aradora. Foram avaliadas a capacidade de campo operacional e o rendimento de campo efetivo como indicadores de qualidade da operação de preparo do solo. A capacidade de campo operacional obteve processo estável em todas as velocidades. Já o rendimento de campo efetivo obteve instabilidade de processo quando trabalhado com 3 km h-1. A aplicação do Controle Estatístico de Processo na operação preparo do solo permitiu identificação de pontos instáveis no rendimento de campo efetivo para a velocidade de 3 km h-1. A existência de variabilidade no rendimento de campo efetivo não compromete a estabilidade da operação de preparo do solo com grade aradora nas três velocidades. A capacidade de campo operacional e o rendimento de campo efetivo apresentam menor variabilidade na velocidade de 3 km h-1.
