Energy performance of a tractor according to the escalation of gears and engine speeds

Abstract

This study aimed to evaluate the energy performance of a tractor-disk set under different combinations of speed and engine revs. The experiment was conducted at the Federal University of Mato Grosso, Sinop Campus, MT. The design consisted of randomized blocks with eight treatments and four replications being 1Ax1550rpm (4km h-1), 5Bx1500rpm (4km h-1), 5Bx1950rpm (5 km h-1), 1Ax2000rpm (5 km h-1), 6Bx1650rpm (6 km h-1), 2Ax1900rpm (6 km h-1), 2Ax2150rpm (7 km h-1) and 6Bx1950rpm (7 km h-1). We evaluated the tractor wheel slip, hourly consumption, operating consumption and effective field capacity. The tractor wheel slip was not influenced by the variation of combinations gear and engine speed. The escalation of gears and engine speed influenced on field capacity of the assembly and, consequently, the operating consumption. The hourly fuel consumption is lower when working with the gear 6B and 1650 engine rpm. Operating fuel consumption is lower when working with 6B march 1950 and engine speed
