Desempenho operacional de um trator na operação de semeadura em diferentes velocidades e pressões de inflação do pneu da semeadora.

Abstract

The displacement speed and the pressure of the tire of the seeder healthy relevant factors for obtaining of the operational acting in the conventional tillage. For this the objective of the present work was to evaluate the performance in conventional tillage in function of two speeds and two pressure of the tire of the seeder. The experiment was driven in the Laboratory of Machines and Agricultural Mechanization - LAMMA of the Department of Rural Engineering of UNESP of Jaboticabal (SP). A tractor VALTRA BM100 was used scored for collection and storage of data. The experiment was arranged in completely randomized in factorial array 2 x 2 with 5 repetitions. They were measured: traction force, potency, forward speed, effective field capacity, reduction travel of the tractor and reduction travel of the wheel of the seeder. The results point that the speed was the main factor in the evaluation, and the potency, the forward speed, the effective field capacity and the reduction travel of the wheel of the seeder were influenced. The pressure of the tire of the seeder in the influenced in the appraised parameters.
