Desempenho Operacional De Um Trator Agrícola Em Função Da Lastragem, Pressão De Inflação E Desgaste Do Pneu

Abstract: Objetivou-se com o presente trabalho avaliar o desempenho operacional de um trator agrícola operando com pneus novos e desgastados em três condições de lastragem e três pressões de inflação dos pneus. O experimento foi realizado na unidade experimental pertencente ao Departamento de Zootecnia da Universidade Federal de Lavras, apresentando teor de água do solo de 25,6% e 14,97 T ha-1 de matéria seca no momento da realização dos testes. Utilizou-se um trator 4x2 TDA, com potência de 65,62 kW (88 HP) no motor. O… Show more

“…As performed by Tavares et al (2015), the data were first analyzed through descriptive statistics using measures of central tendency and Fuel consumption and traction performance are influenced by soil conditions, tire size, load/ pressure ratio, mass distribution on axles and type of carcass (radial/diagonal), angle and height of claws (SPAGNOLO et al, 2013). Moreover, the presence and use of the auxiliary front-wheel drive (FWD) can increase the traction level of the mechanized set (RALALDI et al, 2016).…”
