Resumo:
The sowing is decisive for the cultures, in the no tillage the furrow openers is essential.
The objective of this work was to study the demand of the seeder in function of the speed and of the
angle of attack of the fertilizer furrow openers. The experiment was accomplished in the Laboratory of
Machines and Agricultural Mechanization (LAMMA), DER-UNESP/Jaboticabal, using three speeds
(5,0; 6,0 and 7,0 km h-1) and two angles of attack of the fertilizer furrow openers (65º and 77º), with
four repetitions. The experiment design was delineation completely randomized, with the factorial
array 3x2. Were measured: field operational capacity, forward speed, hourly and area fuel
consumption, drawbar power and draft force. The field operational capacity, hourly and area fuel
consumption and drawbar had suffered effect of the spped, what it did not happen with the draft force.
