“…This is due to the tire's contact and adherence to the soil surface, which may be greater or lesser and may vary according to the inflation pressure used. However, the discussion is different from that described by Amorim et al (2019) when they tested a tractor-seeder set with two tire inflation pressures and did not find an operational speed variation. The result is possibly the consequence of the lower traction force required by the seed drill compared to the subsoiler.…”

For the agricultural tractor's best performance, it must be correctly adapted to the job. Among other factors, the adequacy of tire inflation pressure is one of the most important and may influence the operation's efficiency and productivity. This study aimed to evaluate an agricultural tractor's operational performance with different tire inflation pressures in the subsoiling operation. The study was carried out in an experimental area of the Agricultural Machinery and Mechanization Laboratory of the experimental farm “Água Limpa,” belonging to the University of Brasília. The experimental design used was in randomized blocks with the following values, 206.8 kPa (30 psi), 137.9 kPa (20 psi), and 68.9 kPa (10 psi), of inflation pressure for agricultural tractor tires. The mechanized set used was a tractor model TM7020 2WD MFWD pulling a subsoiler with five shanks, SPCR model, in a Latossolo Vermelho-Amarelo. The higher inflation pressure resulted in greater slippage, advance, hourly fuel consumption, and lower speed and operational field capacity.

As regulagens da semeadora-adubadora são cruciais para a correta distribuição dos insumos, melhorando assim o desempenho operacional. O objetivo do trabalho foi avaliar a distribuição longitudinal de sementes e o desempenho operacional de uma semeadora-adubadora de precisão em função de diferentes pressões de insuflagem dos pneumáticos. O delineamento experimental utilizado foi de blocos casualizados, sendo os tratamentos três pressões de insuflagem dos pneus (138, 241 e 345 kPa), repetidos em seis blocos, totalizando 18 parcelas de 60 m de comprimento e 4,5 m de largura cada. Realizou-se avaliações de consumo de combustível horário (Chc), velocidade operacional (V), deslizamento dos pneus (DP), capacidade de campo operacional (Cco), distância entre sementes (DES), coeficiente de variação do espaçamento entre sementes (CVes) e índice de precisão da distribuição (IP). Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey (P ≤ 0,05). Os resultados indicaram maior Chc e DP pela pressão 345 kPa. Menor falha, dupla, CVes, e maior IP, foram obtidos pela pressão 241 kPa. Cco não diferiu. Salienta-se que para cada tipo de máquina e condição de superfície do solo, seja necessário o refinamento da pressão dos pneus e regulagens da máquina.

Operational performance and longitudinal distribution of seeds by precision seeder submitted to different calibrations of the wheel ABSTRACT: The settings of the seeder-fertilizer are crucial for the correct distribution of inputs, thus improving operational performance. The objective of the work was to evaluate the longitudinal distribution of seeds and the operational performance of a precision seed drill-fertilizer in function of different tire insufflation pressures. The experimental design used was randomized blocks, with three tire insufflation pressures from the seeder-fertilizer (138, 241 and 345 kPa), repeated in six blocks, totaling 18 plots of 60 m long and 4.5 m wide each. Hourly fuel consumption (Chc), operational speed (V), tire slip (DP), operational field capacity (Cco), distance between seeds (DES), variation coefficient of spacing between seeds were performed (CVes) and distribution accuracy index (IP). The data were subjected to analysis of variance and the means compared by the Tukey test (P ≤ 0.05). The results indicated higher Chc and DP by the 345 kPa pressure. Minor failure, double, CVes, and higher IP, were obtained by pressure 241 kPa. Cco did not differ. It should be noted that for each type of machine and soil surface condition, refinement of tire pressure and machine adjustments is necessary. Keywords: pressure; insufflation; fuel consumption; skating; plantability.
