Resumo: The main objective of this study was to evaluate the operating performance of an agricultural tractor operating with new and worn tires for distinct tire weight conditions and three inflation pressures. The tests were conducted at the experimental unit of the Department of Animal Science, Federal University of Lavras, with average soil moisture of 25.6% and 14.97 t ha-1 dry matter at the time of testing. The 4x2 TDA tractor was used with an engine output of 65.62 kW (88 HP). The tires were R1 type with the following features: diagonal (front: 12.4-24, rear: 18.4-30), where the average tread heights of the new tire were 30 and 35 mm for front and rear tires respectively, while the worn tires measured 18 mm and 4.5 mm, respectively. The experimental design was setup in randomized blocks arranged in a 2x3x3 factorial arrangement, with 18 treatments and 3 replications. The results showed advantages for the tractor equipped with new tires. Slip was greater when using new tires due to increased strength and power in the drawbar.

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. Os pneus foram do tipo R1, com as seguintes características: diagonal (dianteiros: 12.4-24; traseiros: 18.4-30), sendo que, a altura média das garras dos pneus novos foi de 30 e 35 mm para os pneus dianteiros e traseiros respectivamente, enquanto os pneus desgastados as garras mediram 18 mm e 4,5 mm, respectivamente. O delineamento experimental foi de blocos casualizados, em esquema fatorial 2x3x3, com 18 tratamentos e 3 repetições. Os resultados evidenciaram vantagens para o trator quando equipado com pneus novos. A patinagem foi maior quando usado pneus novos devido ao aumento da força e potência na barra de tração.Universidade Federal de Viçosa - UFV2013-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/37410.13083/reveng.v21i4.415Engineering in Agriculture; Vol. 21 No. 4 (2013); 379-386Revista Engenharia na Agricultura - REVENG; v. 21 n. 4 (2013); 379-3862175-68131414-398410.13083/reveng.v21i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/374/282https://periodicos.ufv.br/reveng/article/view/374/3821https://periodicos.ufv.br/reveng/article/view/374/3822Spagnolo, Roger ToscanZambillo Palma, Marcos AntonioSilva Volpato, Carlos EduardoBarbosa, Jackson AntonioAlencar Nunes, Rodrigoinfo:eu-repo/semantics/openAccess2023-01-19T13:16:40Zoai:ojs.periodicos.ufv.br:article/374Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:16:40Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
